MTN ghastly customer service

I cancelled a Business data contract, timeously, in November 2022 only to find a billing January 2023. On receiving the bill I contacted MTN again, no joy. After numerous attempts to get this resolved, I finally went into a store that assisted with the query and in April 2023 and email was sent acknowledging the error and advising that a credit request on the balance has been made. Later that month I received the bill where the outstanding accrued balance had been reversed and the balance R0. Forward to June 2024 I see a bureau listing from MTN, with a legal status and a balance. I've tried to contact legal as no other department can no assist as this has a legal status and no contact number for Legal. I need to email, which I have been doing, since June this year. Fast forward to October, I find out the legal status still exists. Again I try emailing and calling. Eventually someone listens, I sent the bill and confirmation of tineous cancelation, get a reference and asked to call back 48 hours to get feedback. Guess what, almost a week later, I can't get a hold of anyone that can assist me. No one has a contact for legal and the one number someone did provide, when asked for a manager, is a call recording that says email them. The amazing part is the complaints exec, Cornea van heereder has this automated recording advertising the importance of customer care. Well here's a wake up reminder for you MTN, you don't have any customer care ethos.
