MTN - Charging ********** amounts

Worst service ever! Call center doesn't answer, MTN Centurion store helps me, but whatever they say the opposite seems to happen. Email get no reply's. ???? Cant cancel my contact due to this Keep having to reverse ********** debits. Legal action soon...? Contact is for a A31 at R499 p/m. From October 2020. That 3 months MTN. Lets do math. 3 months multip**** by R499.00 = R1497.00 Firstly MTN sends me a broken phone, then MTN charges me an early upgrade fee of R4400 when I get a new... wait, the phone I was supposed to get. Then MTN keeps adding random amounts (R1000) till I have a debit order of R7550 coming off ever 2 weeks. Yes, not once and then MTN fixes it, it keeps coming off at random dates. Then have you staff continually tell me it IS an error, but you must wait 3 days to 3 weeks. Now double debit R7550, that's R15100 in one debit order!!! On a Friday. MOST USELESS SERVICE EVER! Also wont give me the ability to port my number, even though it is supposed to be an available option for meto go to another network. Which I will be doing. Trying to keep MY F@CKEN number. DONT USE MTN.
