Hello,I have sent my son renewal application through online on 22 Feb 2022,i have sent old passport next day through 1st class RM to Corby passport office. Once they sent me email to post old passport it was already posted that was 9th March last time, after that I never heard anything at all. I am thinking to call them because now I need the passport urgently. Then I found this page and following it and reading everyone experiences.
It is very frustrating at the moment.
