Review tiling a wall

Satfield came out to install tiles on Wednesday onto one wall in the bedroom. He did a very good job besides the fact of not finishing as had tiles to cut and he said his grinder was stolen. So we made arrangements for him to come on Friday to finish. Thursday he wants a deposit from us.. For the job he charged us R1800.00. On Sunday when he quoted he said he did not want a deposit. On Thursday night he came to fetch a deposit of R800.00 which I only wanted to give him R500.00, but he wanted R800.00. Today is Friday he phones to say he has now had an accident in his car. The worst service I have ever ever had. I am now arranging another tiler who will be more reliable.
