Try contacting your local MP if you don’t get a reply from Shapps. I contacted mine when the delay got silly and got action within a week.I am still waiting for a response from Grant Shapps about the ongoing difficulties a lot of us have or are experiencing.
I never did get a reply to the two letters and an email enquiry from the DVLA.
It’s a terrible pickle and currently, not fit for purpose.
DVLA are a disgrace.
