I got the 4 calls as well..I had just signed up for a quote on health ins..guess I know to never do that again...hope it stops at 4..I never answer a number I don't know..an with no message I didn't call back..just searched the number..you guys are right on about the ins quotes...
This number called me 5 times in a row without leaving a message, right after I got an insurance quote for auto insurance.. shouldnt have given them my number. Thats for damn sure.
