Seabird Tourists — bus got delayed more than 1 and 1/2 hour in the midnight

Hi sir,
My name is chandan i had booked the sea bird bus through travel yaari website from sagar to bangalore (Pnr no.5356862-ts[protected]kjja) scheduled departure was at 11pm. Know it's almost 12.45am in the mid night still the bus has not arrived. Imagine the plight of the customer. Kindly take necessary action against the bus service. Plz guide me on how to file the consumer complaint.
Thanks & regards,
Chandan
