My DD is going on her year abroad in a week, and got an email from NatWest yesterday saying her Visa debit is being swapped to Mastercard and that she will receive the new card in the next 3 weeks, which is probably no good as she leaves on the 25th. She phoned NatWest and the woman said the old Visa card won't stop working until she uses the Mastercard, or if it expires. I already received the new card months ago, and my old Visa one stopped working straight away. It also says on the email that the old one will stop working, so it seems that what the woman on the phone said is wrong. Has anyone been able to speed up the delivery of the new card, or has any ideas of what to do? I suppose she will just have to take cash and either I get on the plane and take it to her or she comes back to the UK, but it's a bit much to get on a plane for the sake of a debit card!
