Mehran, I hate to say it, but the fact of the matter is that there's little you can do here. I've read legal cases of people who went as far as to sue the IRCC (writ of mandamus), and when the matter was a delay in criminality, even the court didn't seem to mind the delays. We're all in this together...I say renew your PR card when you can (as I am doing) and keep waiting.
