I only get child benefit and tax credits as I work but I have those paid into a post office card account. I do have a normal account but like it being seperate to my wage as if I stuff up I know tax credits is in a seperate account.
I have recieved a letter today telling me I have to give them a normal bank account as despite the post office card account being extended until 2021 you can no longer use them 
Has anyone heard of this?
Also the account I have is rubbish so if it is being used for everything I might just switch accounts anyway.
Do you have a time limit to reply does anyone know?
