UPGRAGE FRUSTRATION

I recently upgraded and received my phone on the 4/2/21, two weeks later on the 18th my new phone did not want to charge. I contacted Vodacom online on the 19th and they arranged for the phone to be collected which was done on the 23rd and I received a message on the 24th that my order was returned. On the 26th I phoned them again to find out what was going on and was informed that they will initiate a cancelation and will keep me updated. the 1/03 i again phoned and was informed that no cancellation was initiated and it will be done on the 03/03 i received a message that my service request is being processed by Celest Niemeyer and should be attended to by the 8th, on the 9th I phoned back tp find out what is happening and requested a manager/supervisor to call me back. i received a call and was told that they are working on it and I will receive feed back later that day, i did not but received a call on the 10th it is going to take 24 to 48 hours making it friday the 12th it is now the 14th and it is still not sorted. When is this going to be sorted??? I am now fed up Why was my upgrade cancelled in the first place? when They could of sent me a new device?
