Kingfisher Airlines — Kingfisher airlines overcharging & not refunding

I had bought a ticket with Kingfisher airlines London - Delhi for £589.56(Rs 51,044) on 1st of March 2012. Initially the airlines had overcharged me and debited £611.01(Rs 52,901) from my account. The balance £21.45 (Rs 1857) was refunded in three weeks after countless emails complains, but soon after the airlines informed that they stopped service from London - Delhi and informed my ticket will be fully refunded in maximum two weeks. After an agonising wait of over two months and countless calls to the local office in UK, I have been only refunded with £543.90 (Rs 47,090) which is still short of £45.66 (Rs 3953.2) from what I paid for my ticket (£589.56).
I am currently trying to chase the company for the balance refund but the company has shut down their local office in London without communicating to any customers with outstanding balances and this leaves me only one mode to communicate which is by email. I have sent 4-5 emails to the company urging to acknowledge my request but there has been no response.

The airlines does not realise how adversely people are affected by their decision to ignore customers and stop communication all together. There are much more damages then the amount that they owe me, damages which are intangible like the agony and pain to chase after your own money, changing travel plans and cancelling reservations at the last minute as the airlines cancels the flight, waiting for the refund for three months so you can use the returned money to book another flight. It is a shame how the airlines, who boasted itself on excellence in customer service and communication in its hay-day (remember the advertisements where Vijay Mallya said if you had any complains you could email him directly! http://www.flykingfisher.com/about-us/chairmans-message.aspx), has done exactly the opposite of what they were saying and given one of the worst experiences worldwide to its customers.
