I travelled the vehicle wb19h7677 around 9am on 26th october from gachtala petrol pump & got down around 10.15am in candor tech park, newtown. I called to my jio no. [protected] around 10.30am after realising i left my zte axon7 mobile (Golden colour) in that vehicle. Once it was ringing & after that it went switch off. So obviously i am suspecting that either the helper or driver took the sim card out because when i left the shuttl vehicle only 2-3 passengers were there who also got down within 10.30am. My drop location was little far from last dropping point. So i highly suspect about the on duty driver & helper of vehicle wb19h7677 on 26th october, 2018 between 9am to 10.30am who took my mobile.in the evening i saw the same vehicle was going from my office location, but the driver was different at that time. Shuttl company has not inquired immediately with helper or driver properly or gave any pressure to them to confess the truth. They made me wait till 8pm to be said that driver did not find any mobile.
