Unauthorized Debits on my bank account

Sos squad has been debiting my account repeatedly and when I call the Call centre the service I get horrific. The systems have been off line for 3 weeks. I keep returning the payments but they keep debiting me on random days. Loading a stop order doesn't even work. I cancelled the services I supposedly signed up for a month ago when I received the first debit. I want my money back! This is theft. I will report them and this Luno linked company for *****.
