Bad service

I phoned JJ appliance repairs in Kempton park. Gauteng 0677367991 and I paid them R1200 for a job not yet done. JJ said he needed the money to buy the parts for my Defy Stove. He said he urgently needed the money before 14th January so he could pay for them the next morning. He said he will come at 7am on Friday morning to me. I am still waiting. He said he is on his way but he never came. Then he said he will come early on Saturday 16th January. His phone is off.
