MTN wrongful contract

I'm quite unhappy with MTN's service and ********* behaviour. I have been a customer with them for about 10 years so this is extremely disappointing.

My latest contract expired in November 2019 and when I began making telephonic enquiries to cancel the contract, I was shuffled to different departments and by January 2020 and many promises of calls from MTN - with no return call - and my calling many more times, I was told that I had asked for the contract to be extended for another 2 years without a new device.

I was told to open a ***** case, which I did in February 2020. Once opened I did not hear from them. After many emails on the status of this case, I finally - after prompting from myself again - I heard from MTN ***** in September 2020 telling me to call their retention division to cancel the contract as it was definitely complete in November 2019.

My other complaint is that MTN further needs to reimburse me because they continued to charge me R730 per month for 500 minutes and 2gb of data on an existing device.

This contract should have been +-R200 per month. I want my money back and I want this issue resolved immediately. These tough financial times have made this ridiculous and frustrating with no end in sight.

I want their guarantee that they will sort this out immediately without me having to create a bigger bill and incur further costs.
