Cellphone Collection and Contract Cancellation Request - 1 Month and still no service!

WORST CUSTOMER SERVICE EVER! I upgraded my cellphone over the phone (online) and received the device the very next day - this was on the 14th of December. The day the phone arrived it overheated and I explained this to the Cell-C representative when he called to ask about the phone. I then called the follow up and collections department, the retentions department (084 145) and the customer care department to request them to come collect the device and reverse the upgrade. A month later and still nobody has contacted me to arrange to come fetch the phone nor reverse my upgrade.

On two separate occasions I tried to return the phone myself to my nearest Cell-C store and on both instances I was told to call 084 145 without any assistance, I explained to the 084 145 people that I've called them for a month and still nobody came to pick-up the phone.

The phone was FINALLY collected on the 30th of December 2020, BUT STILL THE UPGRADE HAS NOT BEEN REVERSED NOR HAS MY CONTRACT BEEN CANCELLED.

ON TOP OF ALL THIS BAD SERVICE, THE MONEY I HAD PAID TO CANCEL THE CONTRACT HAS NOW BEEN USED FOR MY MONTHLY BILL INSTEAD OF BEING USED TO SETTLE AND CLOSE THE CONTRACT!!

I have 9 case numbers all of which are useless because a month later I'm still exactly in the same situation as when I received the phone last year December!!!! My case numbers are: 1) *** 2) *** 3) *** 4) *** 5) *** 6) *** 7) *** 8) *** 9) ***

Do yourself a favour and avoid Cell-C unless you want to end up in the same situation as me. My next step is to get legal advise as to how I can cancel the upgrade and cancel my contract! I've exhausted all options with no success!
