Hi mtrows,
I eventually got my passport after 13 weeks and the whole process was a dreadful experience.
I never received any of the promised call backs and none of my complaints were ever acknowledged.
The only tip I would have is just keep trying to get onto the webchat. It’s unavailable (too busy) >90% of the time, but both times that I managed to get on it, my application moved immediately. (Went from ‘Application received’ to ‘Documents received’ within a couple of hours of my giving my lost reference via the webchat, and the second time, went from ‘Application processing’ to passport on my doorstep within a couple of days).
The second one may have been a coincidence as the webchat agent was adamant there was nothing they can do, seems unlikely to me though.
Seems that the people on the end of the phoneline are drones who aren’t interested in doing anything other than reading from a script. If you can type your problem out you can more easily explain what the issue is.
Good luck and I hope that you aren’t waiting as long as I was.
