Who the h*ll is Money Tips taking my money

I am in Gauteng province. I've noticed there went a debit off my bank account for R129.99 reference Money Tips I don't even know who or what they are or what they offer, were do they get my bank details and the authorisation to take money out of my bank account. This is scary that any company can just debit money off your account and you don't even know what of who they are. I want answers or I will make a case of theft open!!!!
