FNB in Collussion with DSTV

FNB is definitely in cahoots with DSTV. We already hear about the collusion with the National Lottery. How is it right that the bank can just allow that anyone can set up a debit order without your authorization. 2 Months Ago I visited the branch to cancel the debit order. The staff confirmed yes its cancelled. DSTV then still debited. I fought for a week to get that refund. I have call recordings and chat transcripts from their website chat with a consultant that its been cancelled. low and behold they now debited my account again. I blame FNB here as how are they allowing anyone to set up a debit order on ones account without my consent. Now no one wants to assist me.
