Mobicred and bobshops advertising false info to **** people in owing money

About 2 weeks ago I saw something I want on bobshop. I did not have the cash and decided to open up a mobicred account to order that specific item. After opening up the account there was a amount charged for the opening. This was not specified beforehand but I accepted it because i did open the account and ordered the item. A few day later I started asking bobshop, mobicred and the seller about the item because I did not get any updates. After a few email with the seller I learned that they are not doing business with bobshop anymore and that the item is not supposed to be on bobshops site. I did email bobshop and mobicred that I want my money reversed and the account closed immediately. After a few days they reversed the items amount but still I need to pay that opening amount of over R600. I believe that this are ***** on their side. Getting people to open accounts with false information and then just keep on telling that I owe it and getting it monthly via debit order. Is there anything I can do?
