How awful calderdale! Sorry to hear about that. A few months ago, someone managed to access my details & take some money from my credit card AND debit card. I immediately contacted the bank, police - and everyone I could think of. After weeks of filling in statement forms, emailing, making phone calls, etc., the bank reimbursed me for every lost penny. Traces showed that someone in Amsterdam'd hacked into my accounts, and was then forwarding details to someone in Poland! If you persist in asking the Halifax to help, they may well be able to do something, but as weeal said, you may not. Best of luck anyway - x
