Consumer Redressal

We had booked 3 nights 4 days trip to goa with yatra.com which had been a horrible experience. We were supposed to board 1.45 pm flight which was rescheduled to 4.30 pm and no prior information was shared with us, we have to wait at airport fr 5 hrs. It almost wasted our entire day. After taking up the issue with them, they agreed that it is fault from their side. To add to our miseries, our return flight which supposed to fly at 7pm was again rescheduled to 1.45 pm which again killed the another day. This time i checked with the airline and they informed that my flight num been changed by Yatra.com and the original flight was in in time and what version yatra gave us was totally different. They said it is from airline side. I have written it to there CEO as well and there is no concrete answer/ solution from them. I want my money refund and need your help to get it done. In short my 4 day has been shortened to 2 day trip.
