Double Billed for December!!!!

Hello there,<br> I cannot understand how my Telkom account is being billed double this month considering that I pay a fixed amount every month and last month I had no service now I have to pay double this month.<br> A credit was issued for the days I had no service, then I get a new bill for December and I have to pay twice as much as a normal month.<br> The client service consultant is still rude enough to tell me that I am choosing not to understand them!!! This is pathetic!!! I demand that Telkom do something about this!!
