Uber — unfair charges

Address:

I, Indore, Madhya Pradesh, 452010

I booked uber auto on 21/07/19 in indore, they showed me ride price 120 and
I accepted the ride. But driver charged me an extra 50 inr for luggage.

We book auto means full auto is ours until he drops us at the destination. But they are demanding extra money for luggage separately, usually, people book auto because of the luggage otherwise we would prefer a bus only.

If extra charges are applicable for luggage they should let the customer before booking the ride or after booking the ride and uber should declare extra amount luggage.

I raised the complaint in uber but they said they can't help me out if i pay cash,
Then why would they give us cash mode option?
