If you google this then the internet is full of horror stories concerning Wonga. It appears that when someone takes out a Wonga loan they give their card details but also they give alternative details of other people as a guarantor. The BIG problem is that the guarantor doesn't have to be present or even know about their details being used. When the person who took out the loan defaults on the repayments then Wonga take the money from the 'guarantor' automatically.
This is scandalous in my opinion, I can't believe that it is even legal! Some people have been taken for thousands and Wonga keep taking it until they have what is owed to them.
So someone has most likely stolen your identity then used you as a guarantor before makingoff with the cash.
