MTN Harassment

This company is the worst cell phone provider in South Africa. I missed my monthly cell phone direct debit on February 1st, 2022. I then paid the account on the 2nd of February. For the last two weeks, I have received a phone call every day, sometimes at 730 am.

On Friday, I spoke to a representative. She admitted to not knowing if I actually owed the money because the system could be wrong. I asked to speak to a manager or a director and was promptly cut off. Today we received an automated message saying our credit score was in danger at 7:45 am on a Saturday. All for a paid account.

How do you run a business when you can't first check and see if the customer actually owes you anything?
