Bad service

Can anyone please assist? This is the baddest service I have ever gotten, signed a 2 year contract with MTN it expired automatically they put me on a month to month but before the first debit order went off I went in-store to cancel I don't want to be on a month to month this is the same place I got the contract from, they told me they cannot assist I need to call 135 and cancel it myself which is blady ridiculous I did that on the 29 June 2023, it was set to be canceled 29 July 2023 it didn't cancel they deducted again I phoned them because I got a bill it wasn't canceled right they will sort it out and refund me that never happened they just deducted from my account again, tried calling asked for my recordings like they say they record all calls, could not provide the recording instead put the phone off. I have no idea what s*** system they have in place. Mtn customer service is probably the baddest. I'll never ever take out contracts with MTN. **** service. Now my account is still active with no data.
