Unable to cancel my contract!!!

I have been struggling to cancel my MTN contract for 3 weeks now.<br> <br> My contract has ended this month but I'm unable to contact MTN to stop it.<br> <br> First I tried calling 808 to try and cancel my contract over the phone. All I get is a woman saying \The call center has been disrupted and they apologise for the inconvenience". And then the line goes dead. I emailed [Email Removed] TWICE with NO response. I even went into a MTN branch to cancel it there but all they could tell me is to phone 808 from my MTN phone. I've been phoning 808 ever since and I keep getting the same message saying the call center has been disrupted.<br> <br> I WANT TO CANCEL MY CONTRACT NOW!!!!!!<br> <br> Otherwise I will have no choice but to stop the debit order and to keep my emails sent as proof of cancellation."""
