Renaissant Stoneworks

I hired M to install my counter tops, new kitchen back splash and trim for my bar. After completing the back splash it was done to low and he advised he would make the adjustment behind the stove which he never did. He also pulled up my tile on the floor and trim which he placed back but did not secure it. I have tried to be patient but it is going on two months and he has still not come to make the repairs. I would like for him to fix the items or refund me the difference it would cost me to have it fixed.He also promised to fix my lawn chair but he has not returned my chair after multiple request.
