Ply Gem Windows & Doors

Where should I start..From day 1 The communication with the Salesman is terrible the least I can say..countless emails ,phone calls not returned.wrong order placed with different size windows.they want the deposit right away!!waiting for window over 2 months still don't know where it is!Customer service not returning any call or if I get somebody to talk to "I'm new,don't know what is going on"? That is the answer..Anyway the sales rep is the worst I have ever seen.. Not telling thruth at all .He must have taken a school how to do it .I can't comment on quality or service yet ,still waiting for window!
