The only advice I can give is to be patient! They do arrive eventually, and we had a longer wait than most, so we know all about it. The other thing is to give up hope, say that they're never going to come, stop checking your emails, and then find them by chance when you're looking for something else. That seemed to work as well!
:lol: Just wait till you do get the visas, then you really have to start panicking! :lol: :lol:
