Residential Home Improvement

I hired this person to remodel my bathroom. The work that was done was terrible and has already had to be redone several times, Now I have more issues, the shower is leaking and the tiles are falling out and it has only been finished for like 3 weeks, The floor was not leveled and a new one put over the old one and it was not sealed and now the water is leaking underneath. I have contacted him and his partner *** on several occasions thru text message and have sent them photos of everything that needs to be repaired. They promised me on several occasions to come and fix the problem and have not shown to do the repairs. I have tried texting both *** and they will not respond. I have also tried calling several times and they have blocked my calls.
