SSI on caller id. Supposed to be Survey Sampling International in Batavia, IL doing survey for Blue Cross Blue Shield. There's no response when the phone is answered just call boiler room noise in the background. Won't give them any info if they did talk.

Picked up on this call and it was doing a survey for Petco.  It took a while for them to answer after I said Hello. Declined doing a survey due to a recent news report exposing how people (criminals) can port a LAN line to a T-Mobile wireless phone, etc.  I doubt this is a scam but I'm not going to risk the possibility.

I get calls every day, even twice a day; never leaves message;

2 calls just tonight 30 mins apart from 630-239-1039 and 630-239-1155. They call daily and when I answer no one is there

Just received one from them now.
