When requested that they stop calling was told "we'll do our best." I voiced my concern that in the past they have called at 7 or 8 PM. "We call until 9PM" the operator said.
With all my respect to Chicago symphony, the tickets distributers are very annoying. They calling me already several months to push me to buy subscription for next year and save the same seats I had during two previous years. I blocking one umber, but they calling from another, and several months they don't give me a rest by calling at different time of a day. If I would like to continue this subscription I would so it on line, don't need any pressure from sellers.
