It's illegal in my state for solicitation calls be placed to a cell phone without written or verbal permission from the cell phone holder or prev or current business relationships in the last 1 & 1/2 yrs.  I do not give my cell phone number out to businesses so calls like this are just an illegal scammer calling.
I report each & every call I get because I do not give my cell phone number out to businesses.

Scammers don't care if the calls they make are illegal.
