me, wife and baby boarded at fathima college madurai yesterday night with our luggages. as we find no place (stand not fixed) to keep our bags in last row upper birth we kept 3 of our bags down. some one near hosur or krishnagiri wantedly took our pink hand bag along with them. we tried to reach everyone and finally one female passenger did not pickup the call from morning till now. we requested bus front cctv footage from the travels. but they are not answering properly. i think its better to book in govt transport and stay awake all night to watch our things carefully. why to waste our money and pre booking in sleeper coach with safety amenities still facing these issues. kindly help and do the needful.
