******* by Telkom on billing.

I do't understand why my monthly premium has sky rocketed from R469p.m to R600 and something rand all because Telkom's business process only allows them to change intsallments date after a month. I got an invoive for June which said i owed the entity R1149.20 for both May and June premiums, I was shocked as the debit order for May was paid. I then call the customer service, when the consultant checks, she tells me I only have to pay R600 and something which i don't understand as my contract/agreed amount is R469. The consultant tells me its for the extra billing that they charged as I changed my debit order last month and the debit order date changes month after you change your debit order date. I was never told of this when taking the contract and all of a sudden i must pay for that. Why is it other entities dont charge for that and they do? It's unfair that one has to suffer for Telkom's business process. Telkom is a *******!!
