I get it. I can understand. I too was expecting next year. My PGWP was ending in JAN because my passport was expiring in JAN. I got only one year in PGWP. I was about to start my BOWP. Probably u should ask for GCMS. and some msgd contact local MP. I think its good idea too
I have done everything i can GCMS notes, phone calls, web forms etc. i am getting only one answer "everything is done on your file just wait for DM. due to covid we are working in reduced hours."
