I have booked flight from goibibo for delhi to pune vistara uk971 10:25 am 25 nov. And reached there before 10:05 but unable to get the boarding pass on time. After this i went to vistara booking counter and reach there at 10:10. After lots of discussion they agree to move this ticket to evening ticket 5:25 pm and i am agree to pay the extra 2650 rs.
But after 10:25am they says the seat is not available and this ticket is also not cancel. I have paid delhi to pune 14928 rs. Now i am unable to get this ticket to move to other flight. And not able to cancel the ticket.
Why i am bear all the 14928rs i want my money back and amount for the next booking flight which is approximately 10000rs. These airlines are looting indian customer. I have seen at the booking counter.
If any travel require for this complaint to resolve to delhi all will be bear by vistara otherwise i will registered complaint in high court.

Why we indian are looting by these cheap company.
