Kwantum Reviews 

Customer Service Disaster

We have bought curtains from Kwantum on 08.11.2025 with a measuring service included. After 2,5 months of delivery time on 26.01.2025, one of the curtains is delivered wrongly as the dimensions taken by Kwantum personel was unfortunately wrong. Then Kwantum gave another 2 months delivery time ( 26.03.2025) on top of that day to bring the curtain with correct dimension. Unfortunately also after 2 months nobody came on the confirmed day, nobody called, no e-mail received. I have tried to contact customer service via website, complaint form, telephone but not able to reach anyone. Only a standard feedback with your complaint is registered e-mail. It is really so disappointing even not being able to find anyone to take you into account. I hope we would be able to have the curtain missing as my son has been sleeping without a curtain for 5 months. I will never buy anything which needs a service from Kwantum anymore and wont promote it to anyone i know.

The employee who assisted me was amazing and super friendly and helpful. He helped me and guided me through the curtains buying process. His approach was excellent customer service. He had empathy to my concerns, listened and provided informative and knowledgeable answers to my questions. ​"

very good shops ,

Very poor customer service and an extremely frustrating experience.

I ordered a table online and chose in-store pickup. I opened the packaging only to inspect the item, which is completely normal to check for damage. The table itself was unused and in perfect condition, yet the store refused to accept the return solely because the packaging had been opened.

I contacted customer service immediately afterwards. It has now been almost a month and I still have not received any response. No reply, no update, no attempt to resolve the issue. It feels like customers are simply ignored once a problem occurs.

This is unacceptable for a company operating within the EU, where customers clearly have the right to inspect online purchases and withdraw within 14 days. Instead of handling the situation professionally, the company has chosen to remain silent.

Based on this experience, I cannot recommend ordering online from this company. If something goes wrong, you may be left without any support or communication.

Friendly, easy, quick and effective communication via WhatsApp with an expertise employee who guide me during the measurements and provide advice and solutions

Absolutely terrible. I bought some items online because I was unable to transport them home from the store. Two out of four items arrived damaged. They were packaged very nicely and the packages were not broken or damaged themselves so they must have been packaged already damaged. I emailed customer service and after not hearing back for one week I decided to text them on Facebook. They replied immediately and offered me a voucher worth 25 euros… the items were worth 160 euros! Ridiculous. After some pushing I managed to increase it to 40 but still a gift card. Eventually I returned one only of the items as the insisted that they had to be returned together. The items were too big for me to bring them together to the DHL pick up point hence why I needed two QR codes, but customer service didn’t want to hear it. So now I am stuck with a chipped coffee table. Thanks Kwantum, will never buy again from you.

One order last year and one last Friday - both with incomplete delivery and no installation, although have been included in the orders.

I have bought the gordijnen.

1. I was promised to get it in 3 to 4 weeks. After 5 weeks nobody informed me. I complained. No one even apologized for not letting me know until I complained about it.

2. The gordijnen were wrinkled and not ironed.

3. There was a strong unpleasant chemical smell coming out of it.

Once again, I ordered a product online, it was broken when delivered. I filled out the contact form but got no response at all. Last time, I received a response right after I left a review here, so let's see if that works again.

Update 3-3-2026 still no response on the contact form even though kwantum responded to this original message really soon.

I never received my order and the costumer service is ignoring me, but they took my money out of my account. Very disappointing, seems like it’s ending up in a lawsuit.

I've placed an order over 2 weeks ago to collect. Still no sign of my order. Already called the store multiple times and they always tell me it's going to take 5-10 working days (which is already way past that).

Contacted the customer service online already 3 times. Up until this day still no reply! Contact me ASAP and tell me where my order is or refund my money.

Amazing window decoration service provided by the team. They assist with everything start to end related to curtains

I purchased window blinds from Kwantum in June 2025. The measurements were taken by their staff, and I was assured delivery within four weeks. Based on this promise, I planned my holidays accordingly.

Unfortunately, the blinds arrived after five weeks—already a delay—and to make matters worse, the size was incorrect. Since July, I’ve been trying to get in touch with customer service to resolve the issue, but I’ve received no response whatsoever.

This experience has been deeply frustrating. I expected better communication and accountability from a company like Kwantum. I sincerely hope they take this feedback seriously and improve their service standards.

Great service and price/quality rate

Good and nice experience

I got a broken lamp because it wasn't protected properly. I provided photo evidence and sent everything to support, however, it's been a while and no one replied or contacted me.

Edit: They did get back to me after approximately two weeks to arrange a refund or sending a new lamp and this time I received it properly protected.

I had ordered curtains for my windows and installation. The first time the guys came to intsall, one of the 4 curtains was missing. The installation guys told me that ive to contact customer service.
It took me forever to reach customer service and when I did, they told me that its lost. So they had to place a new order and a new installation date. This date was one more month from the original date of installation and 3 fricking months from the date I bought the curtains.
The curtains were finally supposed to be installed today as scheduled but NOBODY showed up. I called the contact and they asked me to fill in ANOTHER form.

This is the single most APPALLING and INCOMPETENT service that ive ever availed and I paid close to 900 euros for this. Its unbelivable. I will lodge a complaint with every consumer forum in the Netherlands.

Bad quality item came in a packaging 10x bigger than itself loose in the box with no filling dangling and broken.

It got the job done, just not gracefully. I had to follow up more than expected, and it felt like I was doing more of the work than I should have.
