Unknown R99 debit order

What exactly do I need to do now about this debit order now. On the 01 March 2015 I complained about this unknown debit order which always strikes of every month on the 26th and I don't know this debit order and I never entered into any contract with the company named as BILLION (narration from my bank statement). The debit order striked again today, my next step now is to contact my lawyer and the company will have to pay for all these damages, I always call the bank to cancel this nonsense debit order, this is really creating an inconvenience from my side big time, my next step will be to contact my lawyers about this.
