surely your DOB was on the lost application the could look at that
Also driving licence and passport you cant get more official
some jobs worth not admiring there maybe a mistake on their part, so you are now inconvenienced.
i took my son(who is also called martin) to hospital to get tests done and blood taken and sent away, he was there all morning only to discover that all the test had been done and sent away with my DOB on them all and not his and they needed to redo them because of the error and he would need to come back to get them done because they didn’t check he was 26 i was 50 and no one questioned it
