Air India — Refund amount

I made my booking thru yatra but had to call air india to cancel. So I did. There was a penalty which I accepted. For an approx 80, 000 ticket, the penalty was around 20, 000 and I expected an approx of 60, 000/ That's what was explained to me as well, and these are the cancellation charges as per yatra as well. Then can someone explain why the refund amount is 1993 rs only? Yatra says that's what they received and they don't even have a person to actually talk to. A very rude customer service agent on Air India speaks to me and says to take it up with Yatra. How do I do this?
