I am using ICICI Coral Card, they has an offer of Buy one get one Movie ticket from BookMyshow website. I am using this card since 2 years and could able to catch hold of this offer only 2-3 times. Even though I tried atleast 2-3 times a week to book the tickets.
It always give a message that ticket quota for the day is full and try again or later. As per their customer care its a Bookmyshow site issue, which is hard to belive.
It works in this way Bank reserve some tickets for there users @ bookmyshow, there is daily limit of such tickets. So ideally bank should increase the daily ticket counts if there customer base is increasing.
