Consumer Redressal

I booked a flight on Ease My Trip today for a morning flight at 9:55 AM (flight number 995). However, when I received the ticket, the timings were changed in it because they mentioned flight number 955 instead of the time of the booked flight 9:55 I have been following up the entire day on twitter, calling the customer support of both Ease My Trip and the airlines and it only goes on the auto recorded message with nobody picking up. It is ridiculous how they can mess up someone's time and money and take absolutely no responsibility for it.
