Shocking legal and customer service issue with Vodacom

Vodacom is completely incapable of billing me correctly. They keep saying I'm not paying my bill (which is on debit order, and always has been for 10 years). When I called to resolve it, they said I had to go into the shop and they canceled my phone connectivity. I went to constantia village and paid to be reconnected and settle my bill. However, they STILL couldn't get their act together to clear and balance my accounts. INSTEAD THEY PUT MY BILL TO THE LEGAL DEPARTMENT, DESPITE THE FACT THAT I HAVE DONE EVERYTHING TO TRY TO SORT THIS OUT MY SIDE!!! RIDICULOUS!
