Sorry if this is a dumb question, but how do I dial 2747 5500 from the U.S.? I dialed the U.S. exit code 011, then 800 2747 5500, but I got a recording "we are unable to complete your call, dial 1 or 0 first, then the number." I tried 1-800-2747-5500, but that doesn't go through either.
I'm using an AT&T landline.
