Disgusted and appalled

I cannot imagine that a Company that cannot handle their finances and mismanages their client amounts can still be running. We cancelled our DStv subscription on May and were given an amount that we needed to pay. We paid this amount and have not had DStv since then, but we keep getting calls from their lawyers that we owe money. Every time someone calls, it is a different amount. We event cancelled on their webpage and complained about the bad service which is why we cancelled in the first place. To date we have had no response and we have been handed over to lawyers. I cannot even sell my Explora because apparently we still owe them money - and yet another amount I might add. What is happening in that Company? Can you not cancel a customer subscription after they have paid and just call it quits. Are you that hard up? We have sent all our payments to the lawyers and are still waiting for an outcome.
