I was a subscriber, but I don't like to be pushed on the phone, I can get my decision base on mail, e-mail and just information from friends. Here you can find advise from Chicago Symphony Orchestra representative about calling to ticket office and asking to be removed. IT WILL NOT WORK!!!!! they like parasites will never let you alone. All my very good attitude and impression from concert are screwed up by this people, who calling me EVERY DAY almost, different time, and I blocking all phone numbers, but they calling from new and new numbers again and again, They worse than any other telemarketing
I purchased some tickets online back in 2008, and donated some money in 2009 and 2010. Once I went back to school for my master's I told them not to call me again, that I could not donate to any institution for a while but they continue calling several times during the year. It is annoying.
Missed call. Left no message. If this is in fact the CSO, I've asked them not to call me in the past. They send huge packets of paper mail too. I requested to be removed from their mailing list and was directly told no, as long as they had my contact information they are entitled to send junk. Smart PR move, CSO.
