HomeDisConnect Internet Service Provider poor billing systems

I recently app**** for internet service with HomeConnect. In my first statement I was billed for a talk talk service I never requested. Sent numerous emails was then promised it was going to be removed. I was then forced to pay for that servicd as ' the bill was already generated'. End August for September again the talk talk amount appeared on my statement. I questioned again. No response from the ISP. I took it upon myself to pay what was reflecting on my bill in the app i.e R790 , i paid R800. To my suprise my service has since been suspended since Friday for non payment. I am now told I need to pay R2092,03. First was told despite the proof of payment for the R800 it still was not reflecting on their system.
