Best Concrete in Nashville TN

I asked him to come hang a large and heavy mirror on my wall. I told him it would require two people. He came by himself after this conversation anyway. We had to help him ourselves. He glued this very heavy mirror to the dry wall, which was too heavy for glue alone. It fell off a few weeks later I hear a crash where it fell off the wall. It damaged my dry wall and the baseboard when it did. If we (or the pets) had been in the room we could have been seriously injured. I contacted him repeatedly. He told me I sabotaged my own mirror and refused to come rehang/repair or give me a refund. DO NOT HIRE HIM!
