Makro and defy service

I purchased a dishwasher from makro centurion about a month and a half ago. It stopped working and on the 4th of june i contacted makro as was stated on purchase. On the 8 june i contacted makro to check on tge status of my request. The call centre agent just brushed it aside. I became very agitated and was very upset. I agent put down the phone. I called again on the 9th june. It was also very un productive. I askes for a senior manager to call me. About 20min later the manager called and informed that a job card was logged. This is now 1 week later. I then contacted defy call centre. To this day and many calls later i am no way nearer to getting the machine looked at. They donot want to respond to my calls. I phoned sefy 3 times today No way closer to getting the the dishwasher repaired. What are my options for this poor service feom makro and defy
