Reply about what?
What do you expect 48 to do in such circumstances?
Obviously you need a valid functioning card to buy stuff.
If you have another card then use that.
Or ask someone you know to buy membership on your behalf, through the Gift Store if necessary:
Otherwise you'll just have to wait until you get your new card and use that to renew your membership plan.
If you need to contact 48 support about this then see the links in my signature below but I can't really see what they can do about it.
