They tell you: "If you are confident with doing this yourself" -- if you are not, send it back to PC. I have sent mine back, and it has been sent to me four to five weeks after. PC is not very active at the moment, which should have to do with the Coronavirus flue, but they can repair or replace your phone in London provided that they have enough stock there. I won't be put myself at risk by doing it by myself, and would return the device.
