Slow/Bad service from MTN

On 20/11/2020 I app**** for a new sim card deal from MTN. They sent me a mail back Ref no 14003*** and said someone would contact me. After a few days I triad to find out what was going on I was sent to a few different people in different departments....the answers was always it was someone else's problem.... On 07/12/2020 I mailed customer care for some answers,they got back to me on 09/12/2020 and said they could not get hold of me!! NO ONE phoned me!!! Then they said its all good the courier company will contact me shortly. I Contacted customer support again on 14/12/2020. It is now 16h16 15/12/2020 and still no word...........
