Travel Guru — Booked resort - when reached resort there is no booking from travelguru

I had booked a resort in Wayanad through "Travel Guru" website. I have made a full payment to the resort through travel agency for the dates 15, 16 April 2022. Being 5 ladies in the group and having 2 senior ladies we reached the resort by around 2.30pm. For our shock the resort persons informed that there is no booking from TravelGuru and they don't have any information on the booking. We were shocked as we didn't have any place to stay other than the booking to resort "Jungle Retreat". As it was long weekend we didn't have any option to look for other stays in Wayanad. With no network and internet to connect we were stranded in the place with a very helpless situation. Also as there was a festival in that area there were no restaurants open for that day. We had to manage for our mothers with biscuits that we had bought. It was such a helpless situation without food and even for a washroom we didn't have a place that day. We have been cheated for an amount of 22, 000. More than the amount it was a mental pressure when we visited different state. Please guide me on how to raise and block this TravelGuru.
