MTN CALL CENTRE IS THE WORST - NEVER AGAIN

I am due for an upgrade on my MTN account and this has been the most unprofessional and frustrating experience ever. I called the call centre on the 5th of May to do my upgrade. The agent proceeded with my application and then MTN champion Nokukhanya told me to email her which I did on the same day, with no response from her, I waited few days and called the call centre again to find out how far my application was and then I was told that I need to do the application again, I was then helped by another MTN champion by the name of Ernest, who was very helpful, I then recieved an SMS saying that I need to make an upfront payment of almost R14 000 which made me very confused.... I was told because MTN migrated to a new system the system automatically generates these sms and it has to waiver... But this whole process for just an upgrade took almost 2 weeks of me calling and me emailing and me doing the run around... Which thought it's very unprofessional and very degrading for a customer.... I was told that a supervisor or manager would get back to me up until today I have heard nothing from anyone no email...

I then spoke to Ernest again and told him to cancel the upgrade I would rather wait and then go into the store for the upgrade... He told me that would be the best option for me... I waited a week then went to a MTN store in Ottery and the agent over there helped... I was supposed to have my new device yesterday the 29th May just to find that my application was never cancelled by the online call centre... I called yesterday and spoken to 3 diff agents who all told me that they escalate this matter and make it urgent and that I should wait until this morning and then go to the store and everything would be sorted, just to find out that nothing was done and my application is still active nothing was cancelled from the date I first did the application which was on the 5th of May 2020... How pathetic is that... This has really left a bitter taste in my mouth... To treat a customer like this.....
