hello nellietjie,
welcome to the ppi forum.
This link was given to me by rory who is part of the site team formerly a moderator on retention of records.
http://www.hm-treasury.gov.uk/media/...ations2007.pdf Part 3 19. Record Keeping.
You may be able to use this to press NatWest to explain why they are not retaining financial records in line with legal statutes ie the law of the land.
My guess is they will have the records but will refuse to release as they know the massive onslaught of ppi reclaiming is about to commence and they are up to lose loads of money for allegedly mis-selling.
You may want to contact a site helper on this issue before making a final committment but if you check out the stickies at the top of the forum you will see loads of information and if you check out the links sticky from me you will be able to spend time (LOTS OF TIME) reading and getting information. I would also suggest following a few different threads on people who are also chasing NatWest.
Good luck anyway you can always post and some kind person will pick up an try to help. PPI new issue and a learning curve but we will succeed.
