Mtn ****ming poor customers

Early 2022 i was phoned by an mtn agent telling me i could upgrade my data, i refused and told him i needed a phone for my wife, S22. We went on and the calculation came to around R560 per month. After this telephone agreement he insisted to top up my data for less than i was paying. I agreed. I got so busy with my studies and i never checked the outcome. After 3 weeks i got a bill of R25000 and when I checked it was data of R3600x 8 times which was loaded on my account. I wrote an email to mtn customer care but got a response after 3 months. The matter was not resolved. I wrote emails to oumbdsman , lATa but they referred me back to mtn who in referred me to the Durban agents The Reward company and Mondo, . I did not get the phone and the data was fast disappearing. I complained again to mtn but they only stopped the disappearing data which was now around 200G. They would block my account every month including my 10G data from school. Now they have handed me to debt collectors whom i believe are also part of the ****. I have been paying my account ever since and they are ignoring me for my statement and to solve the issue. I lost a lot due the number they blocked.
