[Allworth]

I've sent a letter to DVLA recently using regular RM 1st class stamp to get an answer from DVLA 3 months later that they 'haven't heard anything from me'.
Had a notice on my letter box to not send any junk mail, RM postman was keen to ignore that, it turned up I had to do fill some paperwork with RM to stop spam into my house, despite polite visual and verbal warning to postman not to behave such.
