I don't use cards a whole lot overseas, layovers anyway, will on vacation. I did call when we went to Germany on vacation. They do have online notifications one can check off.
They should get the drill after a while. The only incident I ever had was with a Cabelas Visa card. I fueled up a private plane near Detroit with fuel, then flew home and bought some tires off Tire Rack. I guess it was to much for their system, off the card went until I called.
I don't use the card you mention. Go elsewhere if they can't get it right.
