Champion Windows

I had Champion install windows and a patio door throughout my home several years ago. In May of this year, I called Champion windows after having my windows cleaned and was told that at least 5 of the windows and the patio door had broken seals. Customer service scheduled a tech to come to my house. He then verified that the seals were indeed broken. He also verified that my patio door which had never locked correctly had a defective lock and would be replaced at the time of window replacement. Couple of weeks later I was contacted by Jerome. He said Champion would not replace my door lock under my warranty. He also stated the windows might take several months to replace. It has been 6 months and I've had no response from Champion. I was able to track down 9 phone numbers for Champion-including Todd Dickson. In the last 10 days I have spent hours calling the numbers only to get the same message-"we will call you back as soon as possible". Ha! No response whatsoever. I was finally able to reach a live person 3 days ago in Minnesota who sent an email to the Denver office to contact me. How hard is it to answer an email? I would never recommend Champion to anyone! The customer service response time is atrocious..
