Great price, intermittent service and poor customer service. Problems happen but getting them sorted is very inefficient and time consuming. - *Update no request received for any info to investigate*

Staff was good finding us a deal that met our needs at an acceptable cost, explained it all well. We dont understand why Three didnt pay the last bill with our previous provider even though it is advertised everywhere that they will. We did ask about it at the time and they were going to look into it but haven't.
Internet and mobile connections are a bit hit and miss. Good speeds at times, other times just buffering or no mobile reception.

Ridiculous Processes - Poor Communication

We have been with 3 for 15 years personally and as a little business and have never had an issue until the past couple of years.

We had 5 sim only contracts many at £2.50 + VAT per month which were amazing.

We then purchased 3 x Samsung Tablets for Engineers to us on the road. The tablets broke so quickly within 2-3 months. We called to inform 3. They told us to return to Canterbury store (purchased store) to resolve issue, the Canterbury store informed us to call 3 business. 3 Business requested we re attend the store. This happened 3 times over a few months with no progress and no one taking responsibility.

Due to this in-action we have now paid for the entire 24 months contact for all 3 devices and only used data for 2 months.

We have requested a refund but we are always passed to the team to upgrade. UPGRADING is honestly funny at this point.

All we want is a refund for the failed service length provided by 3.

We have been told that as we are now out of contract we are not eligible for a refund because of this.

Honestly appalled how we have been treated by a company we have been loyal to for 15 years.

Trying to get something sorted has been extremely tough speaking to people in Mumbai and then being passed pillar to post.

Is this honestly how to treat loyal customers?

Training needed for staff

Spent two wasted, frustrating days trying to sort out a problem.
I have been pushed back and forth from customer services, business services and our local 3 shop.
Not one department will resolve my dilemma.
Each one pushing it to the other, no one will take responsibility for their mistake. I have know wrote to the complaints department, I hope they will reply and resolve !

Avoid Three Business like the Plague

Avoid Three Business like the Plague! They used to be great, with a support team based in the UK that were always happy to help, but now they off shore their support and it's awful. They have policies that they imply but wont share with the user, when you mention complaints they hang up or end chat (even though their website says to use chat for complaints). I was on live chat for 2 hours today and they kept ending the chat while I was typing.

If anyone from three business sees this, I have the full transcript and screenshots that I'd be happy to share
