I am not happy with Green Building Supply. I ordered some plank linoleum from them and it buckled within 8 hours of being put down. I have installed a lot of floors and am very confident in the work I did. I talked to Joel on the customer service team and he told me the floors were either installed wrong or the weather is humid, I live in Florida so that was very possible. He suggested I buy a dehumidifier and when that didn't work I called them again. I also sent in pictures of the damage and they said they would call me back. I haven't heard from them in 2 weeks. My wife has emailed them a couple of time and still no response. I just want my money back at this point.
