Who called from 4052131306

Received numerous calls from this number wanting a specific person.  Anyone else getting these calls?  And what in the world do they want?

I did.  It was really strange.  Didn't identify themselves at all.

i received a call from 4052131306 this morning, i called it back from another phone and the ill-english spoken foreign person told me they were a company who did personal checking of a person, i do not know who the hell this company is, but they better keep their noses out of my business and had better not call back....don't we all have enough to keep us busy that we don't need extra crap to deal with!
