Good luck Chinstroker, hope you get it all sorted. Wish I could give you some tips, but I think you’ve done about all you can. I don’t think the PP Office comunication ‘system’ is there to help us, but just deflect the flak from the local PP Offices.
PS What office did you have to send the PP to? (I live close to Newport but had to send mine to Glasgow, so that hasn’t helped!)
