Account HARD LOCKED when account has been paid!

Vodacom decided it would be a good idea to hard lock my business account today. After 2 attempts (20 minutes) to get through on 082111, I eventually speak to Amier Salie, who as absolutely no idea on how to deal with customers. It turns out, there is a query on my account, dating back to approx July last year, for the amount of R100. I am arrogantly told, and given very little chance to respond, that he will not unlock the line unless I pay 75 % of the outstanding balance. I hope he enjoyed getting his little kick out of his R75 demand!! I have paid the R100, but Vodacom has still not unlocked the account. 20 months and R14000 into the current contract and you lock my line for R100! SHAME ON YOU! Expect these lines to be cancelled in July!
