3 AIPs and client unable to provide information

Compliance are chasing a customer who has had 3 AIP’s since GC was awarded in 2004.
They have requested information back to 2004 but both bank and Ns&I have refused or are unable to provide this information. He has supplied information back as far as he possible can

We have advised Pension service of this but they are requesting that this information be provided.

have the Bank and NS&I have said in writing why they won’t/can’t provide the info

If won’t, it may be challengable - data protection?processing of info? i don’t know

if they can’t, and have confirmed why they can’t, and its credible, then there’s no more info to be provided

Is this because they suspect that something changed between AIPs?

no idea Gareth, just sent them a letter after discussing it with compliance officer,
