Hi Becky
I have heard of this happening before. I hope you got onto the DWP to get your PIP reinstated. They may try and argue that you should have sent it in a week before the deadline - but if necessary, you tell them that there is nothing in their notes that says this, and it would mean you had a week less than the month allowed. If you haven't got it back, or they refuse when you phone, ask for a call back from a case manager. I would also raise this with your MP.
Hope you get it sorted.
