Hi,
sorry to ear that you are in this awful situation, I don't know what to do either!
it's my 22th month "inland applicant", and yesterday I received a letter asking for:
IMM 0008
IMM 5462
IMM 5562
IMM 5669
Schedule 5
Passport bio pages
Police Clearance and
Medical exam.
They only gives 7 days to receive all docs they request.
This is actually the complete file I send to them on september 2017 minus some support proofs. I think IRCC lost my application.

At least I got medical request.
Anyone in this situation?
