Air India has offered an interim compensation payment to Mr Ramesh of £21,500, which has been accepted, but his advisers say this is not enough to meet his immediate needs.
The family fishing business in Diu in India, which Mr Ramesh ran with his brother before the crash, has since collasped, his advisers said.
Spokesman for the family Mr Seiger said they had invited Air India for a meeting on three occasions, and all three were either “ignored or turned down”.
The media interviews were the team’s way of reissuing that appeal for the fourth time, he said.
Mr Seiger added: “It’s appalling that we are having to sit here today and putting him [Viswashkumar] through this.
“The people who should be sitting here today are the executives of Air India, the people responsible for trying to put things right.
“Please come and sit down with us so that we can work through this together to try and alleviate some of this suffering.”
In a statement, the airline, which is owned by Tata Group, said senior leaders from the parent company continue to visit families to express their deepest condolences.
“An offer has been made to Mr Ramesh’s representatives to arrange such a meeting, we will continue to reach out and we very much hope to receive a positive response,” it said.
The airline told the BBC that this offer was made before the media interviews with Mr Ramesh.
