MTN are ******* and continue to debit my account on a canceled contract!

MTN requires one month notice to cancel a contract.

We have been trying to cancel a contract since September 2023.

Still being debited on my bank account and if I reverse the payment, my other contract number will be blocked.

Below is what has gone on:

Notice of cancelation of router *** was sent to mtn on 26 September 2023. Contract was due to end on 26 October 2023. My account was still debited as follows

October 2023 R754, 33 November 2023 R824, 33 December 2023 R754, 33

After sending numerous emails, this contract was only canceled on 08 / 01 / 2024.

I want my refund as I did my obligation by notifying MTN through the right channels and provided the correct notification period.
