On 25th january 2019 in evening time around 8:30 i am going to my home from ctm, at hatkeshwar bridge, ahmedabad i came to know my mobile was stolen from my pocket. I tried to find out around 2 hours but not able to get. I did complain to police station at khokhra, but yet not get any feedback. There is no security system that can find my mobile? Police refuse to file fir. What i have to do?
