Kept getting calls with no message from this number. Today i ignored it and the guy left a message saying, "hello? Oh. That's ok. [***] off." then hung up.
I called the LA Phil - if you want to be removed from the list, you should call 323-850-2046 and ask to speak with the telefund department manager. He is very nice and will listen. Hope that helps.
LA Philharmonic keeps calling me every other day and not leaving messages, but I finally answered today only to hear they are seeking donations. Very annoying!
