MTN is the worst!

I am royally disappointed service from MTN. I upgraded three of my four contracts with MTN in November 2022. One of them was a deal that included two Samsung phones. The phones were never delivered, and I had to chase and chase both MTN and DSV to track where the phones are. The only answer I finally have now in January is that the contract was cancelled. By who? No one can tell me. In the meantime, MTN is billing me R1700 + on this contract (out of contract rates), since November 2022. I am in contact with a "team lead" who is apparently helping with my credit and what is due to me, but once again I have to chase constantly and there have been no updates on my credit. @MTN please resolve my issue, I'm honestly tired of following up and wasting my effort and resources.
