Telkom bills you before sending an invoice!!

Here I am, paying my bills when they arrive every month. The bills are paid via debit orders that go off on my account. When I ordered Telkom to install my land line, they did it in the middle of the month, but started billing me earlier and earlier each month.<br> <br> I came to quite a shock this morning when I saw that Telkom has yet to send me an invoice, but the debit order has already been debited. How in the world can I query or dispute the amount that I need to pay before I receive the invoice firstly and secondly, how in the world can I see if what I need to pay is the correct amount?! What about my credit? What if I had a positive credit and you just bill me. How would I know where the money is going and why I was billed for the amount that was deducted from my account without a valid (if any) invoice?!<br> <br> You are *****ing my money without me seeing why. Invoices help the consumers!!<br> <br> Never is the answer, yet Telkom resides in the upper food chain where consumers can say absolutely nothing. We are the customers and the customers has a right to go and view an invoice to query regarding the prices therein!! Telkom just doesn't give a damn and they never respond when asked nicely.
