Carrie has diplomatically stated the issue here, Inayak. Priceline is a rock-bottom online booking service who spends millions of dollars in advertising to lure travellers to use their service. Most travel goes well, but when there is a problem, the customer is left high and dry. Online booking services are cheap because they give little or no customer service. Priceline is probably the cheapest. I am so sorry that we can't offer more than advice to try to force them to help you. It doesn't look good for you.The problem with purchasing through Priceline is that they may have purchased a heavily discounted fare that Air France is not willing to offer another option for the Jet Airways portion. At this point you are likely going to have to repurchase the Amsterdam to Mumbai tickets and hope for a credit from Jet Airways along with all of their other creditors.
