Stay away from Window Nation!

We've had a terrible experience with Window Nation from the start. We have been trying to have our windows installed since May. A gentleman named Lou came and gave an estimate. Said someone would be measuring within a week or 2, and that the job would be done in 6 weeks total, with labor only being 1 day. Once the measurements were taken in June we stopped hearing from
The company completely. We called multiple times, and only after leaving a bad review in August were we finally called back. Apologies were made and someone said to call another branch. We did what we were advised to do. We called the other branch and left a message and again were never called back. Once again, we stopped hearing from anyone from Window Nation. At the end of September we a received a text from "Tom" saying all products were in and they were ready to start the job. Despite our concerns, we again gave them another chance to get the job done. The job was then scheduled for October 3rd. (Again, we were given our estimate in May). On the morning of October 3rd I received a text from the technician at 9:30am saying he was on a big job and could he come another day. I responded that the job was scheduled for today and that's when we needed it done. We never heard back after that. No response at all. This morning, 2 men showed up at our house. They were not in a company van, not wearing company clothes, didn't speak English, and had the wrong Information for the days job. We were once again, very upset. We asked to speak to a supervisor and we were told there was no one to talk to over the weekend. So apparently, if they book your job on a weekend and something goes wrong, don't expect a resolution until Monday. Given all of these events we did not feel confident that the job would be done correctly, so they were told to leave the property. This is a national. Company that advertises all over Staten Island. Outside of the initial salesman coming and giving an estimate, it has been nothing but a disaster. The unprofessionalism, the rudeness of employees, constant calls trying to get answers as to why in 5 months we still don't have our windows, and the many different excuses for it. There is no excuse to explain how any of this is how a national company does business. And quite frankly, no excuse is enough to satisfy us. We are disappointed and we are angry. I have every intention of leaving this story on every review forum I could find. I will tell anyone who'll listen not to walk away from Window Nation, but to run. By the time I've exhausted all platforms and resources, I will be sure that the time hat conversation is done, the next people won't bother wasting their time they we did for all these months. I should also include that my husband previously wrote a bad review a few months back, and this morning when he went to write about today's events he saw that is blocked and cannot leave any reviews. So this company is also trying to prevent negative reviews on their website, which is doing nothing but duping customers from seeing how this company really works. STAY AWAY FROM WINDOW NATION!!
