This is my second review after getting PIP intially in 2017. I asked for an extension because I simply couldn't do it in time and they extended the submission date from 3rd May to 17th May. I sent a letter confirming the extension via next day registered mail and had a text two days later confirming they had received it.
I sent the full review back with a lot of evidence on Sat 13th with next day registered mail. The same as the first letter. The royal mail have no confirmation of an attempt to deliver and since today is the 20th, without any confirmation from PIP that they have recieved it I am worrying that it has either been lost or refused for some reason.
Should I phone the PIP line and ask or am I worrying for nothing? How long should I wait until I get some feedback from them? My family say no news is good news but that is just causing stress and it is weighing on my mind a lot.
