Hi Sum
You don't sound dim, it's a very valid question.
When you request a Subject Access Request the organisation has to send you all the information they hold against you, names other than your own are redacted, you can at times find out very useful information.
I did a SAR request for AA a while ago, we were able to use some of the information when we appealed, which was successful.
