Debit orders not authorized

I had this rude guy calling me and not actually explaining what the hel he was selling. The guy made it sound like i was owning someone money. As i continued listening to the **** this guy was trying to tell me i kept on telling him that i can not hear what he is trying to tell me. After he kept on telling me that i can decide on tge services after he takes all my details.....booom the debit order sms came through after the call. I immediately phoned the numbers on all the sms's i received and explained to the guy what happend. He assured me that he wil make sure that it gets canceled and they make use of a call center to sell this. And then the debit orders just kept going off....what the hell. How do i get this items canceled and get my money back. If i do a debit order reversal. . . they will try the same **** as loan finder handing me over to attorney's for reporting this to my bank and getting my money back.... activation of debit orders i never did. . . Can someone please tell me how to get hold of this people. Lost the sms's and the only details i have is from the bank Mag zone AFN ********** 4 Save base AFN ********** 4 Deal depot AFN ********** 4
