Reliance Home Comfort

We bought the AC unit and on May 27 and installed on June 5, the AC unit works great and installation is smooth. I would've given the company 10 stars but after the horrible aftersales experience with the sale man who we bought the AC from, I wouldn't recommend the company to anyone. We have two problems after the installation which is not related to the AC unit itself. One problem is the $400 rebate application, it got declined because the serial number of the unit that Reliance submitted is duplicated or has been used, another problem is that the contractor forgot to install the themostat on the installation day (we have an old one is in use, they suppose install a new one to replace it). I have contacted the salesman that we bough the AC from many times and he always give us the same answer that he has already contacted rebate department and installation department and will get back to us when he hears anything. However it has been almost a month and NOTHING was done to resolve the problems. When I fed up with his attitude and demanded a real answer and he told me " sometimes we need to wait for an answer"! It is very unprofessional the way he treated us and I wouldn't never buy anything from him if knew this would happen. I am not picky person and I thought these couple problems (which wasn't even my fault) could be fixed in no time but the outcome is vey disappointing. The AC unit from the Reliance is great and I wish I could give the company 10 stars but I just can't after this experience with the salesman. By the way, the salesman frist name is Chon Houi, I hope you treat you next customer better than the way you treated us.
