Scammer maintenance contractor

Shaun van Der Merwe does General house maintenance. I need to sell my property so I got quotes and asked Shaun to do the job. I paid according to the contract... and even more than I needed to. 1. His work is very rushed, workmanship below the below average. You have to see it to believe it. 2. Very messy and never cleans up. Paint splashes all over my floors as well as furniture He said he will complete the jobs by end of Dec. However, mid Dec he went to Joburg for "another job". WTH. He has still not come back to finish what I have paid for. He says he is trying to find money to get what he needs to finish the job. I, as a consumer am NOT responsible for how he manages his finances for his business. I have paid him for this job, so he should have used that money for all the supplies. Right or wrong?? He is full 9f stories. Do not be caught by this devious man.
