I have been trying to cancel 3 of my 5 phone contracts with mtn since february 2021. I have paid the penalty fees of r7500 for early termination, received pop confirmation for the termination but after more than 100 emails and after more than 10 hours of phone calls to their customer care number, I am still being billed for the contracts. I am beyond frustrated and I am unable to even stop the debit order without mtn's consent. What am I supposed to do???
