Private Bus — unethical and very bad service

I nandini vashisht booked a bus from kasol to delhi on 06.11.18 for 11.11.18and got the confirmation message where it was mentioned that i have to board the bus from sun and wind hotel at 6:30. I reached the place at 6 but there was no bus from srt. Firstly i didn't got any call from the bus service company and when i called the person mr. Preet singh gave me a no. Of pardeep who didn't picked our call and when he did picked up the call after 20mins he said that we have to come back to kasol bus stop. But then mr. Preet singh said that you be there and board a bus of pal bus service. That bus again dropped us at the kasol chowk and asked us to wait for the bus. Out of anxiety when we again called mr. Preet singh and questioned him about his services he said that you take your money back and go home on your own. He also talked to me in a very bad manner whose recording is with me. And when i told him that i will surely him he said in a very arrogant tone that it doesn't matter to him and now i have to go home on my own and cut my phone. When we interacted with mr. Pradeep regarding the same he said that i should go and talk to the ownwrs. The funny part is that the bus that mr. Pradeep made us boarded for which i paid rs. 1200 is the same bus on which a person who paid rs. 1000 is travelling. Our bus supposed to leave at 6:30pm and it's 7:15pm and it still hasn't departed.
