Terrible customer service from Makro Centurion

I purchased a new Defy fridge/freezer from Makro in Centurion, who delivered it to me on 2 August 2019. On Monday 5 April 2021 it stopped cooling entirely. I e-mailed Makro on Tuesday. I received no response until late on Wednesday, when I was asked only if I could be contacted telephonically. Following this, I had the entire motor replaced and re-gassed, at my cost, by an independent contractor. The fridge still did not work as I was informed that there are gas leaks deep inside the mechanism which the contractor could not fix. I had my son’s 9th birthday party on Saturday and had to have a working fridge immediately. Makro did not assist me. I eventually drove to Makro in Centurion on Sunday 11 April. I spoke to the returns office and informed them that I will buy a new fridge now, and expect to be reimbursed the R 6,999.00 for the broken fridge at my home. I was informed that this could be done. I paid R 12,999.00 for a new fridge. By today, 17 April, Makro has just ignored me. This is unacceptable and entirely unfair.
