Castle Windows

I had 14 windows replaced 8yrs ago.. The same 2 windows wouldn't stay open.. this is the 3rd time.. Tech came out and said he had to order replacements parts and it would be 2 weeks.. it's now 2mos and NOTHING. I just called again and was told the service dept is closed and someone would get back to me., Windows aren't that great and I overpayed.. go somewhere else.. don't waste your money here. Horrible customer service.
