Vodacom owes me R6,99 so they handed me over to attorneys

After a prolonged ordeal that created the impression that Vodacom's collection team were working to protect a ********* and identity *****, I went through a further ordeal in trying to get my month to month contract cancelled, which it eventually was. My number was printed to Telkom, my last invoice says that Vodacom owes me R6.99. So imagine my surprise when I got a SMS that I'd been handed over to Hammond and Pole Attorneys. Calling Vodacom repeatedly is an exercise in futility because the customer care team will put you through to Accounts and Accounts will either "accidentally" drop the call or mindlessly transfer you to some other number that requires you enter a valid Vodacom number - which I don't have because I was ported to another network.
