My understanding is that I have paid enough to qualify for the full state pension when that comes round.
Still, if they pester me I'm sure I can get hours of fun out of it.
Oh I do ~ I have a file of letters that even Dippy would envy!

A couple of weeks ago I had two identical 5 page letters, both with 3 identical enclosed leaflets, from the Dept of Work and Pensions (Pensions Branch). The following day I had two more envelopes containing exact copies.
I sent them all back with a polite note saying that one was sufficient and surely the resultant savings would help the Government meet its self imposed economy targets.
Yesterday I got them all back in one large envelope together with a Compliments Slip that said "We return herewith the documents you recently sent us. Copies have been taken"
