In May 2013 I did MRCP part 1

In May 2013 I did MRCP part 1…part 2 end of 2013…i applied for paces overseas 2015 diet 1…got rejected… Then i applied in UK and had my first attempt and failed same diet… Since then, I am applying nearly every diet and I receive a rejection letter… Overseas and UK… I stopped 2 years because of special circumstances… 2020 diet 1 is the last diet before the end of my validity period… I sent many e-mails saying that I am about to finish my validity period… And that I have the priority… But no answer… I called them they said we receive thousands applications… I asked if all candidates who got accepted this was their last chance? Then silence…they repeat only the same sentence without any logic in it.
I am asking if anyone had face the same issue with Paces?if anyone know what should I do or who should I call?
Thanks in advance
