Thanks Mr. Bean and Keyser for your replies. Actually I am currently oversees so cant contact any of their offices in person.

But I received an Email from Kingfisher ([email protected]) which quoted by Booking reference(PNR) as well as my original Email. There are extra charges for rescheduling, which is OK and they are asking my Credit/Debit Card details, so that they can do the need full. Is it safe to give Credit Card details over the E-Mail? I have never done it in the past?

Thanks in advance guys.
