Wow. I'm so glad I googled this number. I received a missed call last night and no message. I keep trying to call back the number and I get a busy signal. I got worried someone was trying to prank me. I guess it must the Met. I bought tickets for April and they keep sending me stuff in the mail. I didnt think they would ever call.
I traced this on White Pages to Global Crossing Local Services, which is a part of Global Crossing Telemanagement, Inc. I went to their website and can't figure out what they do (IP solutions), but it might be telemarketing. Definitely not a collection agency.
Have also been getting calls from here almost every other day, for the last three weeks. No message left. Wasn't sure until reading these posts, but yes, I too purchased tickets to the Met Opera for my parents as a Christmas gift. When returning the call, all I get is a busy signal. Today I flipped the phone opened and listened and heard a woman's voice say: "They wouldn't want to sit over there during intermission." This in fact makes me sure it's Lincoln Center/Met. Time to remove my number from their list.
