MTN's Appalling Service

MTN's Bad experience. I signed in for a contract with MTN early 2019 worth R199 which provided me 40 gigs sim only. The fist 2 month a agreed amount was debited from my banks account and afterwards they started debiting R299 for what I do not know and I was not advised of these changes till my contract ended. During the contract period I was contacting customer service for assistance as they confirm that their system had issues at the store or the consultant made an error, I will be advised numerous time that a query has been logged and sending me to the store for further assistance as I asked for refund. They kept sending me back and front and getting no assistance. I went to the store(Melrose arch) and one of the consultant said this is a complex query and he doubts they may not attend it. I even ask him to keep me posted and till today no action has been take.

Later when my contract expired I upgraded as I was getting billed out of bundle rates and advised them to debit on the last working day of the month in-store and telephonically that was not actioned. I got a text advising me to go pay due amount in store and yet services do get disconnected when they do not debit. This is so frustrating that I have to stay in touch with customer service queue all the time to get no assistance. I'm drained and there is never a point where I missed a payment and I am worried that this may affect my credit record and I want to be reimbursed.
