@proprek1986 @goudam are you guys inland on some kind of work permits, or waiting abroad? If in Canada, have you contacted your MPs? What about looking at your GCMS records?
Either way I would say your situation is unacceptable... When I was waiting for a long time it crossed my mind to really sue the government, but that might not be a good idea, although in your situation I'm not sure what other recourses there are.
According to the information from the Statistical Reporting Group of IRCC, on 31 March of this year, of the February 2020 CEC applications, 1622 were approved, 45 refused, 6 withdrawn, and 256 were "on inventory". Since then based on the reporting on this thread, many of these 256 left over cases were approved, so it seems your cases are unusual even for this very unfortunate group of applicants.
