MTN lacks communication

I write this customer expeirence aggrieved and wretched about the MTN network service provider and they still continue to harass me over something that I have paid in 2023. That is over a year and half now, for some reason there is no communication that they have with their debt collectors which is frustrating because they have even blacklisted me now for no reason.

I state no reason because I have had MTN send Vericred to me in 2023 to make the collection and i paid the full stipulated amount. I would like to have this escalated and addressed as soon as possible because it has highly affected my credit score and credit life. I have been to the MTN legal department physically in Fairlands Johannesburg, earlier this year. I was assisted by a lady called an agent to get a paid up letter from Vericred and now they have handed me to Nudebt on the same account that was closed.

Vericred has provided and confirmed that i have paid up and issued a letter that the account was closed. However, to date I am still receiving calls and emails that I owe MTN. I sent multiple emails with my bank statement, vericred statement and letter that shows that I have settled the amount that was quoted and paid over to Vericred for MTN.

MTN not want to verify the payment I made with Vericred, and have this to be closed off.

I want to know what it is going to take for MTN to acknowledge that payment was made to them through their initiated debt collector and clear my name officially.
