Hi, I have had a letter from Capita to say they have received my completed PIP form and I'm assuming they will now be in touch with me regarding a f2f interview. However, I am going away for a few days and have a friend who is going to do the mail for me, could you please tell me what sort or colour of envelope the appointment letter will come in so he can deal with it for me. I am not going far so am able to come back if it is short notice. Thank yoi
