VODACOM & VVM CAHOOTS!!!

I have never struggled like this to settle an overdue account. So Vodacom handed over my account to VVM attorneys to collect funds. There I am make payments every month end and finally when I want to make the last payment, I get sent a statement stating that I haven' been making payments. I contact VVM and they refer me to Vodacom accounts, accounts refer me to legal, I contact Vodacom and they refer me to VVM. Then I get an email from Hammond Pole to say they're the new attorneys and I owe Rxx which still reflects me as not making payments. So now Hammond Pole is referring me to Vodacom, Vodacom to VVM, VVM to Vodacom and the cycle continues. Mind you that time the interest is accumulating. I have sent emails, I have made phone calls, I have been put on hold for hours, sent POPs everywhere, I have been told to go there and not there. I just nee t know, what must I do to get my name cleared?! Or should I just let it go? Forget abut clearing my name?
