Gem Windows and Doors

Had French doors and retractable screens installed back in 2013 to replace a window. One side of the retractable screen never worked properly and would shut only about half way. Getting a service technician in from Gem took months. When a rep from the manufacturer (not Gem) came to our house he noticed that the screen casing was bowed due to incorrect installation. He removed the screen but said we had to call Gem back to get it fixed. Months later, after several calls, I visited Gems showroom to get answers. My sales rep was not in and I was told I would be called. After I didn't receive a call, I visited the showroom again and met with Jim. Jim came to our house that day to assess the situation and blamed the manufacturer who pre-installs the screen for the bowing. A Gem rep came to reinstall the screen but it didn't fix the problem. The screen still only retracts about half way. I waited a long time to write this review hoping I would have a better customer service story to tell.
