Text - scam or inefficiency

Is it helpful to use the assessor notes from a previous decision to complete a new review form AR2. I have had PIP for several years now and have never seen any of my Assessor's notes. If this is a good idea how do I request the notes?

So I rang Pip this morning at 9 am and within 20 mins a young man from Donegal Ireland answered and he is sending my last PA4 notes which he said should arrive within 5 - 7 days, although the list where I live is very bad. Thanks for your help to date.
