Call Audience Services at 323-850-2000 to get removed permanently from all the lists. If you don't want to be called again, don't buy tickets at the Bowl or Phil, or make sure to omit the phone number section of future orders.
Hollywood Bowl Audience Services representative calling to sell season ticket packages. Seems they get your number from past purchases via Ticketmaster.
I work for Microsoft, this caller tried to impersonate a Microsoft technician stating I was having computer errors and my computer contacted them to report the errors as such he wanted to show me how to fix them. He called a internal business phone line that is never used to conduct public business. This person is trying to deceive callers to obtain access to their computer quite possibly for theft purposes. They are in no way associated with Microsoft..
