No help with canceling CallerTunez

<p>I’ve recently took a contract out for my mother at MTN Secunda branch. Lately when people call there is music playing, and she’s receiving daily messages that she has successfully renewed her CallerTunez. We tried the stop and cancelled options but it doesn’t work. I’ve personally called customer care and have sent serval emails with no help whatsoever, just giving me other numbers to call that doesn’t work. I’ve took the phone into the branch a few times as well and every time they promise that the problem is solved, just to come home and find that we’re still having the same problem. This CallerTunez also deduct money, and we’ve personally tried everything our self to stop this and went to seek help from MTN, which was a waste of time. </p>
