Horrible Experience!

I canceled my month to month contract with MTN in October 2024. I was told I have to call the customer service line to complete cancelation. I have contacted them numerous times, all telling me they can't do it and I have to go to the store, I went back to the store and they told me they can't assist me either. I contacted customer service (all dismissive and rude) AGAIN and have even sent an email provided by one of the consultants. But NOTHING!! I went to another store, and was told to go to another store. How can I pay for a device that I don't even have for 4 months already! I just want this thing canceled. I have a 2nd month to month contract with MTN and feel I should cancel that one too but run the risk of getting debited YET AGAIN for something I would not have!! I just want this thing canceled!
