I got call from same number, recorded message telling me that my account suspended. Please enter your account number to reactive your account. It happened after I went to SF to pieracr 39. I used my card there twice, to buy tickets to go to aquarium. And other place I used my card to pay for boat cruise golden gate-alcatraz. Let us know if it happen to you after you use your card at SF, or they just use random numbers and call them.
