Someone only called me once with this number. Good thing they aren't doing constantly.

Just wait.  It has only been 1 day since your post.  They will call all of the time now that they have your number.  They will want you to take a survey and will continue to annoy you.

They've been calling my cell and I don't pick it up. It's annoying. They have been callling me for the last week. I've blocked them them on my cell. SMH.

Calling is non stop. I do not answer. I will henceforth be setting my phone to block this number.

This may be a new # for a well-established frequent (unwanted) caller - "SSI".
They have clogged two sets of phones (both on "Do Not Call") and 6 of their numbers are already long-blocked.
Haven't seen this one yet. Maybe they're expanding (and/or evading?). I think now that they are data miners/survey takers looking to get personal info to sell. I say this as I've now seen their name not only all over the telephone spectrum, but in emails, etc., too - "survey on health" or "consumers" or "energy" - probably all paid for by all the big money floating around to influence opinion. Not selling magazines. Duly reported to both state and Federal Do Not Call violations - as if anything will be done.
