Incorrect account statement once again

Terrible service once again and I'm sure next month will be the same, as Telkom have *********** stuff working in their accounts department. As we've got two landline number *** and *** at two different locations, which is on the same person. Before, they used to send two different statements and now they put both accounts in one statement, which is unacceptable. On top of that every month, they say they fixed the issue, however it is still there. For example internet package was disconnected with Telkom last month (December) , however they billed me over R1000 for something and thereafter cut off the adsl line. Furthermore, I had no internet for half of January. I don't understand how the bill can be over R1000, if it's only line rental (keep in mind, my telephone land line not working, so there couldn't be any phone calls done) and adsl line.
