Paying for Samsung A50 that I don't have....it just stopped working.

My A50 128gb device went in for repairs @telkom waterfall Mall in Rustenburg on the 22 June 2020. And I received a text saying that my device was awaiting spares on the 26 June 2020. Today Telkom cannot find my device. I received a call 3 weeks ago from Samsung asking if I have received my device, I said no. They said Telkom will call me for collection. So now who is to blame Samsung or Telkom? Telkom and Samsung is this how you treat your customers. The terms and conditions say If the device has been awaiting spares for more than 28 days. My device will be replaced. I received that message on the 26th June 2020. I would not recommend Samsung or Telkom to anybody. This treatment has been the worst. I'm paying for a device I don't have in my possession. Samsung you device just switched off while I sending a text and it never switched back on. Look now, Telkom is treating me so badly because of your device. Telkom you are not loyal to your customers and you do not know how to reward loyalty.
