crazy billing

Why is Telkom trying to debit my account with R726 when I have an outstanding amount of R160 because I paid R500. What the hell is wrong with this company. So you want to debit money for the end of march on the 15th of march. You are starting to **** me off now. I said I want to know the settlement amount for my contract. Neither me or my friends or colleagues or family members will ever take contracts with this ****py company. Word of mouth advertising. I'm sick and tired of Telkom and understand you are not the only service provider. Its amazing how you didn't debit my account on month end of February then now on the 15th its then you decide to debit my account. You damn people are insane.
