I got scammed by Indore police and bookmyshow

So basically this happened with me in indore on 25th December where police was at the venue and we were not allowed to enter the venue even with tickets booked. We all received a message saying that we needed to be accompanied by an adult (literally 1½ hours before the show) and I still did. I had my friends and I had travelled Indore alone for this specific show but they started saying that we have to bring PARENTS. The message we got from bookmyshow never said anything about bringing parents to the show and my three tickets were totally wasted since we were not allowed to get in. We were told that we will get a refund in 5-7 days but it's been approximately two weeks now. I really need some assistance on how to get a refund. Any legal help will be very helpful too. I really need my money back as a refund. I am attaching the details of my booking and the SMS
