ANGRY MTN CUSTOMER

EXTREMELY angry at MTN - I went into their store to cancel my contract to a prepaid. 2 months later 2 debits later they did not do as I Requested - called the call center the request is sitting there waiting for sunshine and rainbows. Call center agent sends me to the Retentions department - hanging on for 30 Mins NO ONE IS ANSWERING the has already been a previous pattern with MTN - they happy to take ur money and don't assist when u need to cancel -
