POOR QUALITY MATERIAL AND WORKMANSHIP

I needed to put up a fence in my yard so I asked Ashwin to furnish me with a quote. He said its R6000 I agreed. I paid him R2000 over 3 weeks and he has only bought material once and each time he said he needed cement and stone and wanted the R2000 I then told him there's no material being delivered into my yard but you always wanting money. He bought the cheapest quality fencing not what I requested he put it up quarter way in my yard. It looks terrible and untidy. The fencing is crossing over with other wires it's bent and looks shabby. I asked him to remove it as it was not the quality i asked for and i requested a refund. He only refunded me R2500 and says that it cost him material and labour so he won't refund me the R3500. That is really not my problem because firstly it's the wrong quality you purchased and the workmanship was terrible. He then tells my mum and my son he will refund me but his under audit and investigation with SARS. He owes SARS R97000 that has absolutely nothing to do with me. I want my REFUND of R3500. In other words he took my money and job is incomplete since January his avoiding me. This is broad daylight robbery and thievish behaviour.
