Billing System is a huge mess

About two months ago I missed a payment and Telkom my bill seemingly doubled to R1664. From R648 to more than double shocked me. So I agreed that they can debit the money and they only debited R1500. I called them to find out why and wasn't given a straight answer. Instead was told to pay the remainder....WHAT????

Now it seems my account is suspended and on top of that I'm told I owe over R2000....I've been trying to get hold of Telkom...but instead I'm told that a consultant will be with me momentarily or rather soon. 10 minutes later....same old song. Telkom's billing system is not only horrible,but highly disappointing. So far they won me over with their data deals...it's their billing system that has left me highly disappointed....
