MTN was of contract *******

I took out a contract on 2 years ago on the 5th December 2022. On the 29 October I called to cancel my contract which was ending in Dec , the consultant advised they would load the cancellation to kick in due course(5th December)

On the 6th December I got a message that my contract has been moved to month to month and naturally I was surprised as it was supposed to be cancelled the day prior. I also received my minutes,sms and data on top of my left over minutes and data left over from the previous month.

I called MTN and was told the system failed to cancel the contract, the person told me that they would raise a request to have the it cancelled, I asked the agent what would happen to my account and benefits, he said I would be charged the end of December for the benefits loaded on the 6th December which I was ok with, I asked him again if I wont lose my benefits when the cancel and convert the number to prepaid and he assured me I would not.

To my shock the 7th Dec , I lost all my minutes, sms, data including what was leftover which I had already paid for and on top of that I have an invoice for the 25 Dec for r2015.31 to be paid in December which by the way is more compared to my normal payment.

I have called to understand why this is the case and I cannot be given a sound explanation, I was told its for the device , how can I pay for the device whereas the contract has ended the 5th Dec? what am I paying for as the benefits were also taken away included data and minutes that I had paid for in November and was left over ? ?????

MTN is trying to rob me and I honestly retreat taking out this contract and would never take another contract with them
