Travel Agency Cheated us

Sir, We were 37 people got a tour Package to Manali by The World Journey, Lucknow. From the beginning onward they were not up to their words. While going they collected Rs.3500/- to bring the bus to the Bus station otherwise they have refused to send the bus. They have promised to give us VOLVO with water bottle and Blankets. But they had sent an ordinary AC bus without any extra service. Regarding Itinerary ROHANTG was included but after reaching there They refused to give us ROHANTG PASS . Our agreement was to give final payment at the Checkin. But 2 days before travel company told me that they will instruct us how to make the payments. Like wise they have asked Rs.15000/- for the Bus to start form Delhi, then We have given them. Then They have asked us to give the rest of the payment to to the Hotel at the time of Check in. But as we had a bad time with the company regarding travel and we felt in our spirit that the company will not provide a VOLVO hence we negotiated with the company that Rs.30000/- will be given to the hotel at check in and the final payment would be given once we are seated at the VOLVO back to Delhi. Finally they have agreed for VOLVO to be given. But to our surprise the final day 24th June 2018 they refused us to give us bus back to Delhi. We with all our small kids and ladies faced a big humiliation. However we have managed to book another VOLVO for us by paying Rs.1500/- per person to Delhi. Now I am asking the company to give us the refund of Rs.1500/- per person(VOLVO amount) But they do not attend my calls and do not answer my mails. I have all the mails and call recordings as evidence. Kindly advice us in this regard. Thanks Ratnaraj
