Pradhan Mantri Kaushal Vikas Yojana [PMKVY] — Trainer at PMKVY Institute- GRIEVANCE ABOUT SALARY

I am Trainer at PMKVY institute since last year 2020. My complaint is that
I have taught a batch and it got cleared this year i.e 2021 but the institute is not giving salary/pay on time till now. And now my batch is completed and I have no new batch ongoing institute is giving me telecalling, office assistant like work and they even haven't allowed me attend ToT training or test.
So I what i am saying if this scheme is not fair with students, it is also not fair with trainers also. And there is no place to tell our grievances. Unemployment is so vast that trainers are also a sort of semi-unemployed people. It is very much worse than being unemployed and employed and not getting paid.
And when your work gets done then make the person's job so worst that he/she would have to resign.
And the thing which is sad is that there is no place where persons like us can tell our grievances.
