Charging me for nothing

I received my monthly bill from Telkom all that should be on there is 3 months back bill which I said I will not be paying the full amount and now my new bill and all that should be on there is the dstv explora.where in the world do you get off sending me a new bill for line rental and internet,please show me where I have had a line from you guys for the last 2 months I have been staying on a plot where you refuse to come install a line for me now u send me a bill saying you have provided this that and the other I no longer even stay in that province so now....I am not paying the previous invoice I will pay I have requested for a reduction as I did not use the full months service and requested well in advance for the line transfer but nothing ever came of that and no one came to me to say sorry we refuse to give you line there I had to keep calling, now you leave me no option as I no longer am willing to use my cellphone to call, and have no land line so im using hellopeter.i have also been requesting for a uncapped 8ta sim no one gets back to me about that so now im done with Telkom,send me a new invoice with a reasonable amount I will pay,and that's that,
