Left no message.  Was listed as "unavailable" on my phone.

Unwelcome call on my unlisted land line @7:55 p.m. on 4/26/2016, There was no message left.I hate running to see who is calling. This is very annoying. I will block it, but really I can only block 250 calls and I keep getting 5-10 calls a day. Sometimes I delete a number from months ago only to have to re-block it. Some of them are the similar exchanges. Thank you for this site that helps us identify these spam callers.

This is a boiler room telemarketer who now has called me 4 or 5 times.  If I don't answer they don't leave a message and caller ID says Illinois Call.  But if I answer you can hear the telemarketers loud in the background.  They say they are from Extreme Concepts and will have someone out to look at your roof tomorrow.  I have told them to remove the phone number yet they don't and have reported them to the Federal Trade Commission.

Even thought they are blocked I see on caller id they are still calling every day.

This company calls every darn day and if not home won't leave a message.  Caller ID says Illinois Call.  I have told Brian & Jay who have called to stop that they are violating the FTC regarding soliciting/telemarketing and they said they won't.  Company calls itself Extreme Concepts and keeps saying they will have a crew at your house tomorrow to look at your roof.  Our police dept. has already warned us about this scam.  It is harassment!!
