month to month contract pathetic

I'm writing to express my extreme frustration with the difficulties I've encountered while trying to cancel my month-to-month contract. Despite visiting a physical store, I was unable to get assistance and was instead directed to call 083 135. However, every time I've tried to call this number, I've been cut off by the customer service and retention department. there is no help at all, MTN is pathetic as their uncapped.

To make matters worse, your system allegedly can't cancel my contract, and I'm still being charged despite, I have the box and modem. This is unacceptable, and I'm finding it incredibly challenging to get a resolution.
