Utterly useless service

I usually receive my monthly statements from MTN via e-mail. However during November, I received nothing. I have been passed from pillar to post requesting MY statement. I received a reference number: *** and was promised this would be sent within 24-48 hours, it is now almost 72 hours later and still nothing. I would rather pay what I owe MTN to get myself out of my contracts with them- utterly pathetic service and I would have thought after all their bad publicity, they would at least try to retain their clients.
