In which case, you would simply get in touch with support and prove your identity and purchase some other way as my thinking is that this would a rare occurence, since receiving a faulty purchase pair using a card that has expired and you no longer hold whilst living at a completely different address is a freak event. Plus, couldn't you still use the expired card as verification even it expired?
