Renewing your HGV entitlement

Just when I thought it was all over,I’d posted of my completed D4 and D47P and licences on recorded delivery on 4th July.Today I received,dated 4th July,a brown envelope from the DVLA with a new D4 and D2 with a letter thanking me for informing them of the non delivery of my reminder!.
I am assuming this is in reply to my letter of 10 days ago to,“The correspondence team”!
(The D2 is for a first driving licence,but can also be used to renew a licence or entitlement.A D47P is purely for the renewal of licence or entitlement).
With only just over a week to go before my entitlement runs out they were not giving me much time!
Anyway,now I have a set of documents well in time for next year!
