Double Charged for tickets

Itickets blames standard bank their supplier for double booking me. All l want is my money and l do not know why l have to confront Standard Bank on your behalf when l supp**** my credit card details on your website. This is a serious breach of my privacy and electronic information as your are not authorized to keep my credit card details after l have already paid you in full. Itickets was not transparent to inform me of this issue but l had to call and email them to get this resolved. So just pay back my money, l really do not care whose fault it is.
