PLEASE HELP MTN, an upgrade nightmare

Following multiple calls, mails and sms's,i upgraded my MTN phone early Septemeber. Post the upgrade, i continued to be called,messaged to upgrade. After complaining to MTN, this was stopped and i was asked to make sure that i had turned off in the MTN app, the options to be contacted by mail,call or sms.On checking the app,all options were in the negative YET I WAS STILL CONTACTED.. After careful checking that my debit order details had been transferred correctly, my debit order did not go off on the 1st of October following my upgrade. I went to the Melrose MTN outlet 2nd October and was advised by the consultant that there was no issue and a double debit would go off in November. Since then i have had multiple contradictory messages from MTN. 1. THE DEBIT ORDER DID NOT GO OFF DUE TO A TECHNICAL FAULT AND THIS WILL NOT AFFECT MY CREDIT RATING. 2. Pay ZAR 1802.35 3. Pay ZAR 636.76 4. At 00.31 13/10 we have had to suspend your ability to make outgoing calls due to non payment of your account.

I went to the store in Melrose this morning and paid the ZAR 636.76 and i will now wait to see if they have reinstated my ability to make calls. All in,i am not surprised, the level of service has been abysmal. I have been a MTN client for over 25 years,dont believe that i have ever missed a payment.
