Yeah I get calls from that number occasionally. It's probably because I contributed to their fund once so now they want more money!

Definitely is New York City Ballet trying to give you special offers that they can "only give you via telephone, not via email". You'll have to ask them not to call you back and be clear about it. I told them they were calling my cell phone number, and no thanks I wasn't interested but that I'd get back to the ballet as soon as I could, and thanks for calling. I wasn't clear enough with my message because they called me 2 days later-didn't leave a voicemail, but I will answer next time and tell them not to call me anymore because otherwise the calls will keep coming. I'm happy to support the arts, but not happy to run over my allotted cell phone minutes.

Called my pay-per-use cell phone.  I didn't answer, and they didn't leave a message.  It would have cost me $0.99 plus 10 cents a minute if I had answered the call.  I have no idea who they are, nor how they got my number.

No thanks.

This number is from New York City Ballet, and trying to sell you the tickets.
