Mtn worse experience!!!

For the past 8 months i have been having problems with mtn without any solution.Debit check mandate being processed on my debit date on the 15th of each month but with fail. Every time JAB payment requested by mtn consultant when i call the next day when debit failed, because of mtn not debiting on my debit date. What is more frustrating is i call customer care everytime an incident transpires and promise that the following month my bill will be updated.Which now im under collections every month because of this issue.I always do follow-ups on this matter but with no joy. Different mtn consultants will always have different stories,like in June i was told to do a cash payment which i did and received a message that my next debit order will be in 20th July and to my surprise mtn set a debit for me on the 3rd of July without my consent. Next day spoke to one of consultants on the 4th of July and explained that the system sets the debit automatically on its own after a cash payment.

My problem now is not the debit but the debit date 3rd July which apparently i was told the system automatically sets it when my debit date is 15th of each month. To my surprise today midnight 22July at 00:10am I received a message stating that i have made an arrangement to pay R26611,82 which i did not.The only debit i knew was my monthly amount of R1405.9 to be debited on the 20 July so since its the weekend debit will fall on a Monday 22/07/24 which again mtn failed to debit again and that resulting me a bad payer who always misses payments.I called customer care to resolve the isssue again i told them that ive already made EFT payment on my mtn app.i was told my line will be suspended since that money will reflect the next three days so basically whos fault is it?

This mtn data sim contract is fustrating i know have to deal with a bad record and will be listed as a bad payer which im not it’s because of mtn negligence.I have been wanting to upgrade my data plan but I can’t do that because now im told that my account in listed in collections.
