Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Arbitration Texas

I went on a cruise with a friends family, we applied for credit cards onboard the ship. The whole cabins charges were billed to my credit card. When I received the bill I contacted carnival and they sent me a document that I have attached, which clearly states I am not responsible for any of these charges. At the bottom it says there is an asterisk mark placed beside the responsible party, which you will notice is not me. There is only one charge on my folio card that was automatically put on there for $48.00 for service gratuity.. every card was charged this. They put the charges on the wrong mastercard. I am not responsible for any of these charges.
