Uber India — driver took our belongings

We were coming from indirapuram shipra krishna vista at 11:15 pm and we kept our box in cabs dicky. Driver dropped us near arya samaj mandir, krishna kunj extension and without givinh my box he ran away. Driver name ia kamta and mobile number is [protected] and after that we called him several times but he didn't receive the call. It's such a horrible experience, which kind of service you are providing. First the driver said he will return the box but now he is refusing to return.
Please take some action other wise i have to file fir against driver and i will go to consumer forum also
