Thought, I should update the situation.

Kingfisher airlines have rescheduled my itinerary. I received an E-mail from them and they asked for my Credit card details. I E-mailed them the required information and they changed it to the required date.

For you guys information, I used a "prepaid" Visa Card instead of regular Credit card as I was bit worried about sending information through E-Mail, instead of secure website. Anyway I am somewhat satisfied now.

BTW Thanks for your replies. Maybe the moderator can remove "pathetic" from thread title. Looks like Kingfisher staff is trying their best to keep it running.
