Son is 16 gets dla,I'm the appointee ,recieved letter to confirm I'm still going to be appointee and completed then receive a letter asking if he wants to claim pip and must phone in by a deadline.so we do. Payment hasn't been made and a lady phones saying there's a contradiction. I phone up to sort out but they now say a visiting officer has to come and fill the appointee form until payment starts.this is standard practice.is it?
