Vodacom debt collections

I have requested for an itemised bill from the start of the new upgrade I had with them. Even the lawyers they handed me over too cannot seem to get this out of them yet they insist I must pay for a bill which I had countless issues with. Now this bill has interest and no-one at Vodacom knows what an itemized bill looks like. I AM NOT RESPONSIBLE FOR VODACOMS INCOMPETENCE. All attorney's handling debt should request sufficient information from these companies before taking on the debt. Some of us are actually innocent.
