MTN - Anyone home in the call center?

MTN call centre absolutely useless. 3 attempts to get through all ending in a deadly silence. Have been battling with account issues since renewing the 24 month contract. No itemised billing statements received even though that was requested with the contract. Now there is a message that I have insufficient airtime on a contract with a limit that has never been reached in the past and cannot get through to find out why. Cannot make international calls since the upgrade. One continuous disaster. Come on MTN - get your act together and get hold of me - or you‘ll have one less customer to worry about tomorrow!!
