TERRIBLE UPGRADES SERVICE AND CONTACT CENTRE EXP

I received a phonecall from Carol (MTN contact centre ) telling me that my account was in arrears!. This is false since my account is debited monthly and recently it was DOUBLE DEBITED ( which was sorted out ).<br> I challenged Carol and she then said it was a misake! My concern is that MTN blacklists me because their accounts are not up to date! I wanted to speak to a manager and Carol tells me that all managers are in a meeting. How can you run a call centre with no managers/teamleaders on the floor??? Either MTN call centre is severely mismanaged or the manager didnt want to get off his / her lazy backside and take my call!!! Both are unacceptable! I've also smsed for an UPGRADE since my topupcontract is up for renewal TWICE but no one has gotten back to me....its been longer than 48 hours!! MTN service is on a downward spiral and upgrade deals are not competitve anymore! What the hell is going on MTN???
