Monthly billing for cancelled subscription

Conversing and reasoning with King Kong would have a yielded a much better result than dealing with you and Showmax. There is something grossly wrong with the both of you. I cancelled my subscription with Showmax and you still billing me. Showmax acknowledges the cancellation but ALASS!!! YOU REFERE ME TO THEM AND THEY REFERE ME BACK TO YOU!!! THIS HAS BEEN GOING ON SINCE DECEMBER LAST YEAR!!! WHAT IS WRONG WITH YOU PEOPLE???
