Hi Denby,
Thank you so much for your thoughtful and helpful message. I phoned the PIP team this morning and was told that I would receive the PA4 in 1 - 2 weeks. Although I know that the DWP was wrong to not award me any points for physical help, and this makes me angry, I won't be doing a MR because I did still receive enough points to get the Enhanced Rate for both components. I realise that I should fight the DWP, because it is appalling that they have ignored the medical evidence which proves my need for physical assistance, but I'm extremely ill so I cannot face it. Thanks again for your kind advice.
All best wishes
