Atrocious after sales service -Hisense

Worst after sales service EVER! I purchased a Hisense fridge via Takealot, which only worked for 10 days. Upon wanting to log a return, I was not able to, since it had to be handled by Hisense under the warranty. Since e-mailing Hisense, I have had zero feedback from them, it was up to me to constantly phone for updates. I was told on Wednesday 18th Mar’26 that the credit had been approved and a courier would be contacting me to collect the unit. By today Monday 23 Mar’26, I still had no call from a courier or Hisense, so it meant calling them again, just to be told again that a courier will contact me to collect. So there is no arrangement to collect & at the same time delivering a new replacement unit, no a credit will be passed & I must reorder a unit. All this whilst I have guests in a self catering unit sitting without a fridge.
