MTN's Pathetic Account Dept

Here we go again! Either MTN has the slowest system or the slowest staff. How long can they take to allocate a payment and update their systems? I paid my account yesterday morning via 1 of their platforms the way i always do and today they have the audacity to send me an sms that reads:

"Y'ello. This is a final reminder to pay R 299.00 to stay connected. Your services will suspended in 1 day if we have still not received payment. You can pay with MyMTN app or via ABSA, FNB or Standard Bank. Select MTN and use A*** or * as your payment reference"

If this was the 1st time, I couldve still looked the other way, but its not. 2 months ago they didnt allocate nor pick up, it seems, a payment I made for more than a month!! Seriously?! They advertise and promote all these "easy" ways to pay but what they dont tell you is how long it will take to reflect on your account while they in the mean time send you notices and warnings everyday about suspending your already paid account. Pathetic to say the least. I now sit with a useless suspended phone and got myself a pay as you go simcard from another service provider to just get by while MTN decides to start working.
