Unauthorized debit orders from my account

Unauthorized debit order going off my account two months in a row. I do not have a DSTV package - cancelled in Dec2017, then suddenly in April and May a R385 debit order is being deducted. After about 5x calls to the contact center, emails to ********** etc. NOTHING has been solved. The call center agents cannot assist me, they don't see the payments reflecting, then things get transferred to a supervisor and then NOTHING. It costs R40 to dispute a debit order, so you are not only costing me time on the phone but money as well.

It is ******* to debit my account without my authorization - so please stop doing it. Even if you have to manually remove my account from your system, go for it.
