Gujarat State Road Transport Corporation [GSRTC] — The knob to stretch the seat is missing

Hello, Jeet here.
I had booked a sofa seat in the sleeper bus for relaxation purposes. But here the knob for the stretch of the seat is missing by which the seat un-stretch to its normal position at 90 degrees.
If the know is knob is not working then the sleeper sofa is worth less. And I had sacrifice my sleep is other thing.
So I am requesting for refund or customer satisfactiory action.
