I cancelled DSTV 3 days before payment date, debit order still went through , I was told it was submitted to banks 5 days prior to payment date. No problem, I understand that. Refund was processed and paid. Great so far. Then next payment date they again charged me, this time for the refund they paid me as well as following month. Consultant on chatline simply says I am active , no cancellation! Went to office, have to stand in street because they say they are short staffed. Send message online, still waiting for response.
