New carpet install yesterday. I thought the install look good, but while vacuuming I noticed buckling around a register. Taking a better look, the carpet isn't attached to the tackstrips in several places around the room. You can just pull it up. You can also pull the carpet up in the middle of the room a good 3/4 and it goes back down slowly. Installer also broke my vertical blinds and said nothing about it. Carpet store is having the installer come out and talk to me about the problems. Any suggestions on how to handle the installer when he comes back to fix the issue?
