Hi dwm
I would try and contact your local authority and explain your predicament, they may tell you to continue to use your old blue badge for the time being. I had to contact my local authority last week and after a short wait someone did answer the phone and resolved the issue. Make sure you make a note of the name of the person you speak to and the date and time.
