MTN South Africa customer service does not exist

If I could rate MTN South Africa with negative stars, I would. I immigrated to New Zealand in 2019 and in 2020 my contracts were up and I wanted to cancel them. MTN South Africa customer service and retentions team are useless. No one takes any ownership or accountability. It is impossible to get through to the retentions team via the phone and when someone does answer, they hang up. I have emailed MTN every month for the past 8 months and they continue to direct debit my account, despite an email confirmation that they had cancelled my accounts in September 2020. The customer service and retentions team do not answer emails and I even went as far as to cc in the CEO and COO and still have had no response from anyone at MTN. When you ask to speak to a manager you are put on hold indefinitely and no one has responded to a complaint I submitted through their website over 4 months ago. I have tried to get some assistance by even reaching out to the MTN team via Twitter and Instagram, but it’s been no surprise that I have not had any response. To this day, MTN continues to ***** money from my account and does not respond to my emails or any attempt that I have tried to reach them.
