Horrible after sales service

Horrible Customer service and after sales service. We bought a 65” TV from Makro in June 2020. TV recently switched off by itself and we logged a call with their head office on the 17th of December. We even bought an additional warranty on the tv. We were promised that a technician will come outbin 3 to 5 working days. We followed up 3 times during the week just to be told today the sorry the suppliers are closed and will only open second week of January. We tried contacting the Centurion branch but they pretty much told us that it is not their problem!! We were loyal customers, but never again!!!!!
