Calls multiple times a day and no one there if I do answer.

Same here.

Can something be done to stop this? Does the state of Illinois have anything in place to stop these people? I would like to take legal action against such and will continue to investigate until I can stop this....my number is unlisted and they have no idea who they are calling.

Been receiving calls from this number off and on for about a month. I never answer knowing it's not important. Today I called back to see if I received a voicemail to determine who it is. The voicemail picked up immediately with an automated voice saying "Please leave your full name and number to receive a call back". It does not state what the company is or who you are leaving the message for.
