As far as I know, they just put the PCN on hold for 2 weeks. We have seen people with your situation before, although most people do get a move on when the video is received. I'm afraid it is your tardiness that has lead to this situation, and I can't see any way out of it, frankly. You could try ringing TFL and ask for an indulgence following your misunderstanding of the process. There is nothing in the next stage, (Statutory Declaration), that would allow you to get the process reverted.
