Worst ever MTN

They don't deserve a star, worst service ever. August 2023 I took uncapped deal of R499. In store when you have to pay, you pay for the month you have it and upfront payment for when you cancel you have that. First month goes great have data no problem till deduction day then they cut me off. The money they get but I'm connected but no internet access. I called call center, the store, call center put you through, on hold then my airtime is up, put on do the same to be placed on hold that they access my account to be cut off. Menlyn store doesn't pick up. For 2 weeks no internet access, I'm far from Pretoria. Long story short after Facebook messenger helped and I still have no access I message that I will return it. At store I get paperwork a copy and salesperson inform me they will call me next day, still waiting for them to call. After MANY emails and calls a email came through asking my imei number, I informed I still waiting to hear from them, he follow up and the salesperson slipped up, October I received a call from him to apologise. I returned router 2 and a half weeks enough time to stop deduction but they still deduct and I pay bank fee, when I email to ask to stop I get automatic reply, I'm fedup for trying from my side to sort this out and they don't care. I heard I have to pay cancelation fee, but I'm fully against it because they got money but cut me off, I have to pay my neighbour to use his wifi. Then I get message routers in for repairs but it wasn't broken, they cut me off. Till today November 20th I didn't received any call from headoffice to sort it out. I want my upfront payment and September deduction back and if it goes on like this the bank fees and my airtime. I'm frustrated, I was referred from one place to the other Scorpion refer to Ombudsman, from them I'm referred to ICASA I'm waiting to hear from them now. Mtn do no effort to get in contact with client. They should stop deduction as asked many times, refund full amounts and no cancelation fee then I'm done with them.
