MTN Clearwater (Contract Cancelation)

I upgrade my contract on 20/09/2022 at Clearwater MTN Branch, I was not happy with the upgrade, and cancelled it immediately in store, did not receive any handsets (Phones) Bongi the Manager at Clearwater Store assisted me. She immediately sends an email to the retention department. Up to today MTN is still charging me for handsets that I do not have. I have been fighting and phoning each and every day without success, Retention Department is directing me to the Store, and the Store (Clearwater Branch is directing me to Retentions. I am fed up, why is MTN not sorting out the problem, Clearwater Manager is fed up with me, that she does not even reply to my messages or calls. MTN your service is terrible. This is such a small matter that can be resolved very quickly but everyone I talk to is trying to Shiff the problem on the next person. (Anne) ***)
