Incorrect billing

After over 15 years of being a MTN customer I have received a service horrible enough to leave and NEVER look back. I have 3 contracts with MTN and got an upgrade on 1 of them in June and the consultant didn’t cancel the phone that was being upgraded and as a result I was being debited for the old phone and the new one. After countless calls to MTN trying to resolve this since July the matter is still pending to date. Every consultant I speak to tells me a different story. I resorted to reversing the debits and paying via EFT and confirmed with a consultant that it was ok to do this but now my service was suspended and they telling me it’s because my payment hasn’t been allocated yet. I now have to wait for them to “escalate” which they have told me so many times before but still nothing happens and meanwhile my work is suffering while I wait. The call center consultants along with their managers don’t know what they doing and nobody is willing to take accountability and resolve any matter, going in store was also a waste of my time because all they did was refer right back to the call center. As soon as I’ve settled my contracts I’m leaving and never looking back. MTN HAS THE WORST CUSTOMER SERVICE and I doubt any other network provider will be worse than this.
