Incomplete Project and will not return my money!!!

So lets hope there is enough characters. I will try to keep this as accurate as possible. So I paid these guys for my pool repair in full an amount of R60k. He fitted a pool pump that is not working. He fitted the DB board that is not mounted and water keeps getting in and tripping the main house. He installed a light that is not yet connected. They were supposed to do the paving which was started and not completed. He refused to come and finish the job stating the reason as me giving him a bad review and he also refuses to refund me. the pool is still leaking. Do not trust this guy - make him do the work before paying him a cent. Do not be a fool like me and pay him. Now i got to get lawyers which is an extra cost for me wall while my pool is still not sorted. I will send a link to pictures and the full story soon which evidence. I hope this will help people.
