Yatra Online / Yatratrip.in — Hotel booking confirmed with ref no.[protected]. but no room provided by the Hotel

I have made hotel booking through Yatra for hotel stay on 9th June 2022. but when i reached hotel they told they have disconnected the linkage with Yatra 2 years back and so no booking can be accepted with that. They also did not provide any room and so I and my relatives had to stand in mid of road at 11.pm which is very disgusting . Being a pioneer online website for hotel booking i never expected this type of service from Yatra. My Entire family members were in a miserable situation midnight and we come outstation with a faith that we have made the reservation and everything will be ready. I have paid Rs. 4034 towards booking of three rooms for that hotel room. Further when I sent mail as complaint regarding this with ref. no TG:31945130 they agreed to give me refund, but even after 20 days there is no response from their side.
