What a complete nightmare and shambles. I can't understand why any of this should be an issue for passport renewals, as everyhting must have been in order for the original passport and subsequent renewals to have been processed.
It seems everything was running relatively smoothly when the renewals were being processed in Liverpool, but the move to Corby and obvious gaps in the staff training have to lead to many issues, like yours.
I hope you make a vociferous complaint once everything is resolved! Good luck.
