Mechashinsen in Edmonton

I have had nothing but issues dealing with the warranty department at Sterling. I have sent multiple emails and left multiple messages and I have not received any response. The latest issue I am dealing with was that my roof was leaking, and water had pooled in a light fixture on my second floor. There is also a water stain on the ceiling around the light. I called and as usual, no one answered. I left a message explaining the situation and asked if I could have someone take a look at my roof and attic to make sure there's no water damage as it's likely there is. As always, no one called me back. A few days later my wife calls me freaking out because there are people on my roof! I get her to take pictures and let me know the name of the company. I contact the company and they inform me that they were contracted by Sterling to fix my roof. No one told me someone was coming to fix my roof. No one told me someone was coming at all!! I never received a call or email back about having someone checking for water damage and still I have not heard anything from them. Now I am having leaking along the wall in my basement and I'm dreading trying to contact them again. I'm so sick of Sterling and I really really regret buying from them!!! I still need someone to check if there's water damage in my ceiling. Why am I being ignored? Another thing I remember is that I told the warranty inspector that my daughter's rooms are extremely cold in the winter (the walls are nearly iced) and I was told that it's because they are over the garage and I should just turn on my garage heater. Are you kidding me??!! Stay away from Sterling if you want any sort of help after your purchase.
