Well at least yours was tracked. In my situation, both Royal Mail (says it will let me know when passport office has got it) and the passport tracking service (it says send old passport, despite me sending it on 3rd January) both don’t seem to say if anyone of them have my old passport. Mine was sent on 3rd January by 1st class signed in. Either it’s got lost or it takes such a long time for the passport depot or Royal Mail to update their tracking service. I have no idea what I should do in my situation. Shall I wait for a couple of months until I get my new and old passport back (that’s if I get it back!!) or ring up their hotlines to find out what is going on?
