On air *****ulent debit orders

I paid my contract in full and cancelled the contract with On Air in November 2021. For two years no communication was received from On Air, but for the last two months On Air is suddenly deducting a debit order again. ***!? No contract, no DSTV, but this company is *****ulently deducting money from my account! What the hell is going on with the employees in the accounts department of On Air and whose name can I use for the ***** case at the SAPS?
