Two of my DC’s have EHIC cards that have expired. Mine and my DH’s, and the other DC’s are still well in date.
I can’t apply for cards for the DC alone as they are under 18.
I just tried to apply for myself with them, but have received this automated email to say that I already have a card. How do I get the DCs new cards? Of course there is no contact number or email to ask. 
Help!!
