VERY POOR QUALITY OF SERVICE AND THIS STUPID MyMTN App!!!

In January 2020, I made an EFT Payment of R1650 to my mtn contract account via the MyMTN App. The App returned an error just after I made the payment. I then attempted to make the payment again but I still got the same error. When I checked my bank account a few minutes later, these ****** debited that R1650 twice from my account despite my payment not going through on their app. I made a number of calls to a number of calls to mtn to get a refund! They kept telling me that the amount needed to reflect on their system first before they could assist!!! THEIR APP SENT ME CONFIRMATION OF THE TWO PAYMENTS BUT THEY CAN'T SEE MY TRANSACTIONS!!! Now i had to suffer because of their stupid app that can't do proper error handling! Over 3 days later! I called them again! I was told that the payments reflect! I requested a refund and I was told i have to wait 7 working days because i could get my money bac**** Again, an inconvenience from their stupid buggy App! The refund request was logged. I called them at the 7th working day to follow up on my refund request! Expecting to be told that i should expect it that day as promised!!! To my surprised, I am told that there's a notice for me to send a proof of payment! THIS WAS NEVER COMMUNICATED TO ME!!! I'm only finding out about this when i call the day i was supposed to get my money bac**** NOW I NEED TO WAIT MORE DAYS TO GET MY MONEY BAC**** I HATE MTN SOO MUCH FOR THIS!!! NOW I CAN'T ATTENT TO MY OTHER FINANCIAL COMMITTED BECAUSE I RE**** ON THE KEE*** THEIR WORD THAT I WOULD GET MY MONEY BAC****

JOINING MTN WAS THE BIGGEST MISTAKE!!! I WANT NOTHING TO DO WITH THIS SERVICE PROVIDER AFTER MY CONTRACT ENDS!!! ****** ******!!!
