Air India — confirmed ticket boarding denied and now no refund

Address:

Mumbai City, Maharashtra

i booked ticket with air india in the name of Mr P R YADAV with air india pnr no J6341 for mumbai to kolkata and return for 23/12/2014 and same day return. the passenger was not allowed to board the flight and was wrongly told that his ticket was a waiting ticket and not confirmed. Later on enquiry we found that the airlines has made excess bookings for the flight and so not allowed my passenger to board and was sent home.. We are fooled by the airlines and later by not giving the refund of the same till date. The total amount of the ticket was around 20000 Rs which is still pending with the airlines as they are not even giving us the refund amount.. The agency is offering us No Show refund which is just merely taxes and i have been totally cheated by the airlines... Pls take strict actions against the airlines company who is responsible for the same and help me to get full refund for the same as the boarding was denied to the passenger due to airlines excess bookings...
