MTN's Bad service and Poor retentions team

I have just read a couple of experience from here and I'm appalled by the service we get from MTN. Rest assured if they make my number prepaid , I'm changing back to Vodacom. either way I'm changing.

These decent agents told me contract was cancelled before they upgraded without my permission.

After holding for 3 hours , i got ahold of someone , Upon the second request to cancel , They didn't cancel. I sent over 8 emails and I spoke to a lady on the phone who confirmed its cancelled. guess what ??ITS STILL NOT CANCELLED AND THEY DEMANDING MONEY. I spoke to an agent who was so incapable she couldn't answer my questions and said she will request a manager to call me. I've requested to speak to a manager 3 times since they don't take calls and still no one got back to me. I am now asking MTN to refer back to those recordings for proof of confirmation and all of sudden they all don't know what I'm talking about.

How could your retentions team be so poor you cant even get back to someone? initially I just wanted to go on prepaid but still remain on MTN but now i want to change service providers.

Can someone get ahold of me so i can resolve this and move away from you.
