Terrible service. Emailed service dept. to a certain employee - 3 or 4 times to simply get an update on my order. Never rec'd an order number and bare minimum update. Employee doesn't sign her name to emails?

Long story short, it took 6 weeks to finally get 2 windows that were under warranty. GM even stated the windows were there at the shop, after service dept. stated they would be shipped to glass installer. When the installer drove 60 miles to pick them up, they couldn't find the 2nd window. Seemed so simple.

My first clue? When the new windows were installed, they never gave us window screens and try getting them after the fact didn't happen. Good quality windows but the problem starts at the top. Manager told me he "wouldn't commiserate with my problem"? What kind of customer service response is that for someone who has been waiting over a month? I told him "someone should"? How about, "I am sorry, ma'am, there has been confusion. I'll get to the bottom of it and make sure it corrected"? I should have just paid someone else for the glass although it was under warranty.
