*********** accounts and billing Department

On 27/08/2019 I logged a complain with mtn accounts for the ridiculous amount they have billed me on 3 of my contracts that's R308,66PM and I was billed R2526,65 per contract. I was given a reference for my complaint which was as the agents says "escalated" 30 days later my complaint was not sorted and mtn debits my account for R6978,81. Now I'm left short because the billings and accounts department were sitting on their hand couldnt be bothered to sort their mess up. I contact mtn business to have my refund done and yet again I'm met with nothing but incompetence from those responsible for my refund. If that's not enough I see again the billings department have billed me incorrectly R708 when my contract is R308,66PM, which means again on 1st of the next month the incorrect amount will be taken off my account. This is ****************! Mtn cant just keep over billing me a keep taking money not due to them off my account. If I dont pay my bill mtn will suspend my account immediatly but when they take money that not due to them I'm supposed to wait! That's totally unacceptable! This level of incompetence is ridiculous and unacceptable and from what I have read it would seem I'm not the only dissatisfied customer. I have commitments and others Bill's, is mtn going to fit the bill when my other debit orders are unpaid or my utilities are cut off because I cant pay the bill, for crying out loud MTN you have taken out over R6000 out of my account, some of us live on a month to month pay cheque to make ends meet and your staff are so *********** that they couldnt sort this in 30days day and I am left short and it would seem that I'm gonna be faced with a similar problem again at the end of this month. I think maybe it's time to move my corporate account to Vodacom because clearly mtn does not understand customer services.
