Indian Railways — non disabled in handicap coach

Address:

Thane, Maharashtra, 401207

I am nathanael, son of a handicap certificate holder shilpa nitin thakor. Even after i have a first class certificate, i have to get into the handicap coach as there are more non-disabled people in there. My mom usually boards 8:23 churchgate center handicap coach from naigaon platform number 2. I have been having quarrels with these people daily. Their reason for getting in here is "hum log roz aate hai" so 1 lady who is 100% fit and another group of ladies who say roz travel karte hai. My mom is even able to reach the seat, has to come standing in a handicap dabba. There is no tc and the rpf officer who came outside the handicap coach was just asking people if they are a handicap. As if someones gonna say no i don't have a certificate.
What's the use of a handicap dabba if they are not able to sit or stand freely.
