Air India — I'm complaining about my refund which I haven't received till now.

It's been 3 months I am waiting for my refund from Air India but neither they have replied nor they have taken any actions. I booked a round trip from Chicago to Delhi on the day we had a flight we couldn’t show up to Chicago because of the delay of our connecting flights to Chicago. We immediately called the Air India customer care to cancel our flight and the representative suggested not to cancel the tickets and assured us that we can take the returning flight of Air India from Delhi to Chicago. While taking the flight from Delhi Air India said that we cannot fly because we didn’t show up on the first trip. We told them that customer care of Air India said not to cancel the whole ticket and without cancellation, we will be allowed to take the returning flight from Delhi to Chicago but they didn’t agree. And we had to book another flight. This matter needs to be escalated. Customer care representatives have recordings of each and every conversation. I need my refund because we had been looted by Air India. This is not Ethical to misguide a customer. The customer care service says something and the ground people working for Air India says something.
