Disgusting service by DSTV, performing an unauthorised uncommunicated debit

A debit of R1113.43 has been conducted on my debit card, this has resulted in my account being placed into debit and a penalty of R105 being implementedby my bank due to insufficientfunds. I have only performed payment for streaming services using my credit card. About 20 years ago I had cancelled a debit facility for Mnet. Without any consultation or notification they very conveniently debit the account for a dish service which has not been connected. I am still only using streaming service. What a shady company that really do not know what they are doing. Please can we not get a different company to supply sport channels
