Very very bad customer service

I made a payment on my MTN account on the 11th of June 2020 which according to the email I received from them was the settlement amount. I requested that they close the account and send me confirmation that the account is paid in full and CLOSED. They ignored all the emails and calls I made begging them to close my account. 3 months later, they send an email demanding that I pay R432.00 for them to close the account.

I have suffered for years trying to pay this account and all they did was harrass me. Now they even blocked my number AGAIN. But I have paid they still want more. They are ****** because they only care about Money not the customer.

I DO NOT OWE THEM ANYTHING.

I am sick and tired of MTN!
