Rebecca,
I was in a very similar position to yourself, so I can understand the concerns you have....
What happened with me was that I got the message that the password was incorrect (it wasn't because I use
an automatic password generator) and I was following the password reset procedure but wasn't getting an email back.
So I then sent an email to:
recruitment.technical.query@royalmail.com
telling them the password reset wasn't working and I needed to book an interview. An automatic email came back saying they would respond in 48hrs!!!!
I then phoned recruitment on the number that has been in various threads (but which from recent comments appears to have been disconnected or
gets disconnected when they are busy). They said I wouldn't miss out on the interview and would get back to me.
Guess what - I'm still waiting for that call.....I managed to book my interview by randomly trying the password
reset very early on a Saturday morning and all of a sudden it worked! My interview was on the Monday!!!!!
I'd keep trying the phone number and also suggest sending an email with 'URGENT' in the title, explaining your problem to:
myapplication@royalmail.com
Sorry I can't offer a better solution - some of the wiser heads on here may suggest other solutions.
Good Luck
YB
