House painting

Hi I got Fabian and his wife to come give us a quote to paint our house. Everything sound great look like they knew what they where talking about. The house is old so I know there was a lot of work that to be done to the house. They told me I only need like 4 drums of paint and some other thing I had to get so got everything they wanted. I end up getting like 8 drums of paint. They did the work but there was a lot places they missed they said they will come back and do it they did most of it but the 2 big walls where so bad looked like they never even painted the place ones again I call him to ask him to come fix it after I paid him in full. I am still waiting for him to come fix it. It’s been more then 2 month now and still no body. And now I see some of the wall r cracking again. I am not impressed with the work and telling me they will come back to fix or a phone call to say sorry we will come fix. I will never use them again.
