If you have a call blocking device or phone, the newer ones have some area code blocking which is the best way to block a lot of these so long as you actually don't need to call or do business in the area code.If not, you can look through this thread.

This is SSI Survey Sampling, a marketing research company. To get removed from their call list: URL is http://www.surveysampling.com/.
Keep in mind that if they do not place you on their internal DNC list, they can still get into trouble. As a rule, survey's are exempt from the DNC though. Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.
This is a sleaze ball outfit. After I blocked their initial calls from 618-248-3568, they how call using this number. A legitimate survey company would not do this and a Google of the 618-248-3568 indicated a florist in Caseyville IL, and this number a florist in Carlyle IL. I wish this site had another Call Type of scammer as these people are after your $$$.
