vr ur rite there still asking me for dosh from 8-9 years ago always made me laugh when you got the letter from them saying this is not a demand but plz could you contact us,so you do and guess what the reply is,if you dont pay ur committing an offence as the inland revenue now deals with it(or is it just for self employed people) andy iirc corretley you might have to pay your bank to do a search for the old bank statements,but im sure the ni would be able to help coz they have to sort out how much youve paid in to get a full pension so THERE must be records held by them
