Took the money but didn't complete the job! Its now been a month since I had 2 new floors installed. They were short 2 lengths of T-molding and the installers said they would have it in a couple of days. Called twice a 5 and 7 days later, 2 service tickets written, no response. Finally filed a dispute with AMEX (love these people) and $500 was disputed as the job was incomplete and written on the installers invoice when they left. I finally got a call back a week later from Tim Whalen, from the Tampa market. I missed his first call and immediately called back, no answer and his voicemail box was full. He called me back. I told him I could not leave a message and he said it had something to do with their corporate voicemail system. Its a cell phone, no sale. After a brief conversation, he was going to follow up and get back to me. Over a week later, I called to follow up. Could not contact, his voicemail was full. Tried a day later, voicemail still full. To date, job still incomplete. I also addressed the indoor/outdoor carpet they installed was rippling. He said it was a different installer (Arthur) but he would reach out to him and have him call me. Yep, you guessed it, no response from him either. Will NEVER use them again! DO NOT PAY UP FRONT!
