Oh yes - DWP are calling me on Sat morning to review her pension credit and that I need to have all her finance info to hand.
As they had the incorrect number on the letter I called them to give them my correct number.
I told them that I have all info to hand already but would they take it off me? No!
They called me this morning and I have to say the lady on the phone was very nice and patient, although it appears that they have still not updated my sisters' care home address on their systems!! She told me it didn't matter because I am her appointee and that all my details I gave were correct (why then, when I rang last time and gave 'them' her postcode - which didn't match their records - did they tell me that they couldn't continue with the call?).
Anyway, everything went ok and they said they would contact me to let me know if there will be any changes to her pension amount.
I am paranoid about 'looking after' other peoples' money (I also look after Mums' affairs) and religiously keep all receipts etc etc, but she said it was fine that I 'look after' my sisters money in my own account (albeit a separate one from my own money) as I am her appointee - phew!!
Think I may be watching too many documentaries where people fiddle the system and get done for money laundering!
