MTN contract cancellation

MTN customer service is pathetic.

I sent an e-mail on 3 March 2025 to cancel my contract which expires on 26 April.

I sent this e-mail well in advance to make sure that I give them more than 30 days notice of my cancellation.

In my e-mail I said I don't want an early cancelation, but I want it cancelled on the day it is supposed to end.

I then received e-mails to say that it will now be extended to June, never mind get cancelled.

When I phoned on 27 March 2025 they informed me that a cancellation was scheduled for 3 March. I then sent an follow up e-mail and they now tell me that it must be 30 days notice, which I gave more than 30 days.

This is ridiculous! I will never open a contract by MTN again
