Run around for service cancelation

I sent an email in December requesting cancelation procedure. No response was received expect for the automated response with Ref number. It is almost 4months later and still the service has not mlbeen terminated. They deducted close to R1500 in February and still request more money. I've spoken to several consultants and the last one Aman *** told me he is escalating the issue. That was on the 24th of March. I haven't heard anything from this trash of a company since then.
