GoAir — Flaw in Ticket booking website leading to wrong booking.

Address:	Mumbai City, Maharashtra, 400006
Website:	www.goair.in

I went to book a return ticket on www.goair.in on 3rd Aug16 for Mumbai to Delhi & Return, i choose the Mumbai to Delhi flight for 7.50 hrs for Rs 3155 for 6th Aug16, i went ahead to choose the return flight, after looking at the options i decided to fly back on a previous day so i clicked previous day, i choose my flight on that day and completed my transaction. When i saw my email i was shocked to see that i was booked on the first flight departing at 6.00 hrs from Mumbai to delhi. I went to the website and did the same procedure again to realise that on choosing next or previous day on the return ticket, the website automatically changes the first flight chosen to their default or cheapest flight. This is a very easy way for the air line to make extra money by changing a choosen flight in a round trip booking on its own and cause wrong booking with the passenger and then ask him to pay cancellation or changing charges. I contacted the call centre within 5 minuted of the booking and explained the matter but they said they could not help. They told me that i would have to pay the resheduling charges of approx Rs2000.
My Booking Reference No is NTCB04. change required is from 6.00hrs Mumbai to Delhi, to 7.50hrs Mumbai to Delhi

Hoping for the company to correct its website design logic, so as not to inconvenience their passengers, and change in my ticket.

Thanking you,
