Air India — cancellation of flying return mileage ticket

Address:

400076

I had booked flight redemption ticket number [protected] using my flying return mileage account for flight on 27th september. The flight plans were changed and i called air india and cancelled the reservation. I was advised that i have 12 months from date of booking to either provide fresh travel date for which no charge will be levied or i can cancel the ticket for which a penalty of 750 mileage points will be charged and balance will be refunded.
I am now advised that air india has suddently changed its policy with effect from 1st of november with no information and that i can no longer use this ticket and that entire mileage points are lost.
This is a typical bureaucratic style of air india
