I am experiencing this now for the second time. The most annoying thing is that they never emailed me to inform me about it. They simply refund the amount to your credit card and that is it. I called them to ask them about it. The guy on the phone lodged a complaint and told me to wait for a response. Still waiting for that.

My gut feeling says that indeed certain countries credit cards are not liked, but also the fact that I never buy any of their insurance nonsense makes me less liked as a customer, so they can do without me.
