Happy Reno

Hired Dmitriy to do a basement reno, when it came time for 2nd installment which was a prepayment, he said he would finish my basement within the week. I paid the $12k installment and he didn't do the work. Left a huge mess in my house and outside. He kept saying he is coming back next week and didn't show up. Would ignore calls and text occasionaly to say he was coming back soon. Some of the work that he did was not proper and actually created more work in repairs. Pics of empty space in basement that was supposed to be a kitchen and garbage he left outside. Kept promising to remove it and never did.
