Customer DisService

My account is paid via credit card which means every 2 years I am required to update my details with service providers as expiry and cvv change. On 23/12/2014 after I had received the new information I attempted to call MTN 808 as, unlike with NashuaMobile previously, there was no \easy"way to change these details. After waiting an inordinate amount of time I left an email with Customer Service indicating that I needed a callback to amend these details. Fast Forward to this week. I start getting threatening sms from MTN saying that my account will be suspended for non-payment. I decide to hold on the line (808) only to be served a half an hour later"
