The worst customer service ever!

My mtn contract has expired after 2 years. I have been with mtn, on the same nr for more than 20 years. After I received the e-mail to go and upgrade, I went into a shop to go and do just that. I was informed that my profile does not exist with them and even though they can see my statements from the last 2 years, I do not have a contract with mtn????

For the last almost 2 weeks I have spent hours, on the phone to the call centre (135), I have been to different mtn shops, 4 tickets have been logged and escalated countless times. A request has been logged with their systems depatment. The only answer I have received is still, that I do not have a profile with them. I have tried to cancel my account with them in order to migrate to Vodacom instead. I am not able to do so, as they say, I do not have a profile with them. I have tried to cancel my debit order with my bank, but this can only be done from the mtn side. The full amount for my monthly contact....which has already expired, was deducted from my account on the 1st of Nov 2022.

Complete incompitance, no help from anywhere. The worst customer service I have ever experienced. Useless!!!
