do Airlines have the right to disclose refund information to a 3rd party?

[scout32]

Following on from my previous question, the airline we booked with disclosed the fact that a refund had been paid onto my credit card with the exact amount and the last 4 digits of my CC number to my "friend" by e-mail even though I booked the tickets and it was all in my name with my contact details, they also gave her the booking reference number before her flights were cancelled, so she could if she so wished have cancelled the whole booking, the airline have told me they have done nothing wrong, should I take this matter further with them?

I don't think they have done anything wrong - I'm assuming that as your friend was supposed to be flying with you that the airport had her name already so knew she was one of the party?

If they had given her your credit card details that would be different but they only gave the last four digits which are useless on their own.
