No Customer Service!

I have been trying to upgrade my MTN cell phone contract, what a challenge! In one of the stores I was told that my monthly account was overdue and therefore the system blocks the upgrade. I printed, and brought back the proof payment and it seemed that it was never processed on my account? Very sufficiently, the lady assisting me, emailed the proof to customer service, and promised feedback within 24-48 hours. This was a week ago. I could still kind of absorb slow service, we are so use to it, but this was the 5th MTN store I have been to for my upgrade?<br> One of the stores did not have stock of the micro simcards.<br> One did not have stock of the phones? (NO SAMSUNG S6) <br> In one store I had to wait almost an hour.... I left!<br> One store was discussing the contract options when they told me they just went offline and wont be able to assist me any longer.<br> After finally getting to a MTN store that was online, had stock, had simcards and enough competent staff to attend to customers, they dropped the bomb of my account not being of to date? ***?<br> <br> I tried phoning customer service 808, on Friday to see if I could sort something out? I was kept online for 45min!!!<br> <br> I AM DONE MTN!
