Hostel Authority is forcing us to join mess and pay full bill.

I'm doing B.Tech at a state government college in Chhattisgarh and staying in a hostel. The mess food here is so disgusting that more than half the students stopped eating there and switched to tiffin services. But now, the hostel authorities are forcing us to rejoin and eat their shitty food. They’re saying that whether we eat from the mess or not, we still have to pay the full bill, plus a three-month advance! Before college started, they told us we’d only have to pay for the days we ate and could submit a leave application to get the bill adjusted. But that was complete nonsense! Now, they’re charging every student the same amount, even if someone submits an application. They’re scamming us! What legal action can we take against this?
