ACCOUNT IS PAID BUT STILL SHOWING OUTSTANDING

I have 3 TOP UP contract by MTN and my account is always debited via debit order. In June this year I cancelled the debit order due to banking details change and paid via EFT for June July and August,<br> I keep on sending proof of payment to [Email Removed] AND [Email Removed] [Email Removed] [Email Removed] and my account still reflects as outstanding. <br> <br> my account has been blocked Nemours times and unblocked but still reflects as outstanding. <br> <br> this is by far the worst service I have ever received. + I send them all the proof of payments from January till September + they show outstanding amounts that you cant even calculate ( its top up contract the amount should be the same) <br> I was refuse to upgrade over the weekend because of this..<br> <br> my account is up to date I send all the proof of payment what more do they need. This is affecting my credit score for no reason and they need to fix this today <br> <br> Cell c Buy out deal sound like a good option now MTN SUCKS BIG TIME.<br> BUNCH OF IDIOTS WORKING THERE AND NO ONE WANTS TO HELP YOU.<br> <br> I WANT TO THROW THEM WITH THIS PHONES AND STICK IT UP THERE ASSES!!!!
