I signed a contract with this company to replace 6 windows for around $5000 in Jun 2016. After adjustment to the contract, they owe me a refund of around $500. However, their salesperson never responded to my multiple inquires after the work is done. I have contacted their headquarters and sales office, and I still haven't got my refund in Sep 2016. Looks like have to sue them to get my money back. Be aware of this company. You can search my BBB complaints against them.
