The normal pathetic South African service from Defy

We bought a tumble dryer on 27th December 2020 at makro. I have had problems 3 times since .1st one was in Feb some thing to do with a heating thermostat.2nd time was in April /May one of the Finns in the drum broke off.3rd time was in July/August the tech came out ,I was not there they said they needed to order a new drum .I have been phoning just about every week since .ref number is ***.have been promised they will call me back even a manager promised to call back after 20 minutes. Two days later after I threatened to go to social media I got a response that they would be at my house today 8/11/2021. Surprise surprise nobody came . Am at my witts end with this absolutely pathetic nonsense. Vanessa if you read this hang your head in shame. I will now seek legal recourse.
