Indusind Bank — Buy 1 get 1 Movie ticket offer

I tried to book movie from bookmyshow site through indusind bank platinium visa card. but whenever i tried to book the movie ticket it shows the message that "Sorry, the quota for the offer you are trying has been exhausted. Please try again later. Please check offer terms and conditions for details or check the support section at https://support.bookmyshow.com". I have tried to the movie tickets at midnight also but it shows me the same message. At the time of selling the credit card bank tole me that you can buy 2 movie tickets at the price of 1. we are providing you an Buy 1 get 1 Movie ticket offer on this platinum visa credit card. But now whenever i tried to book the movie tickets it shows the above message. This is a cheating with the customer by the bank. I am not the only person who felt cheated by the bank on this site there are so many people who filed a complaint against the bank for the same problem. So i requesting you to please take a look on it & take some serious legal action against the bank for giving the fake offers to the customer for selling their products. Due to this customer feels cheated.
