I have had this problem with Chase Visa cards before and email / phone conversations with multiple people have failed. In fact they had told be they do not block any transactions that need VbV. I have always failed to be able to use it for any online transactions on India based sites (where it is a legal requirement for vendors to use 2-step security). Only Amazon.in has been developed intelligently where it holds the transaction and a call to Chase CS and it gets processed automatically. Once that was done - Amazon.in does not require any more authentication / VbV non-sense for some reason.
