drakes flooring

Nick came over to put down sub flooring and tile our bathroom. At the time, we were very busy with major surgery, and have been busy since then, When he was done, the job looked neat, but I walked on the tile and it was creaking. He said he could not easily get to the bottom of the floor from the basement, but "it does not matter, they all creek like that...;If you have a problem, just call me;Well sometime after surgery we did, and do have a problem! Just like I thought, the grouting is coming out all over the bathroom floor!;So I called him! He said he would come but never did. Then we set up another date, a Wednesday 8/22,18 after numerous attempts to get a date for him to come and live up to his word;He did not show that day, and did not respond to numerous calls, texts and messages.;I talked to his wife a few days ago and she said she would ask him, but I never heard anything. It is a simple job, and I told him we have the grout. Now they will not pick up the phone at all. Good luck if you want this kind of help, better to let the work go undone.
