I did a job on the customer property. I asked to clarify multiple times if painting would be needed on the patching work when it was done. He always said no. So I completed the job, and he refused to pay claiming fraud stolen funds and incomplete work. His family have taken to the internet to slander and smear my company as a result. What can I do to get paid for the job and is there anything I can do aboutvtgd smear campaign?
