Unauthorised debit order from ****s

On May I app**** for a cellphone contract over the phone, I found the contact details at Facebook and decided to apply. I was called, an application was made and at the end of the application i was told it is declined. To my suprise end May a debit order of R159 went through and again on June they also took my money. I am warning everyone to stay away from these bunch of ****s.
