You will "not find much about who has called you", I have searched for them as well, with little success!

I DO know this much:  They may be:  Platinum & Associates, in colloboration with:  Davis & Associates (S. Calif.) (possibly a law firm in S. Calif.)   As far as associates are concerned, this in itself is "fraud"!  There may not be "any associates", other than (1) person posing as a association of a group of associates!

Platinum & Associates have a address (bogus or not) in La Habra, CA.  (Near Whittier).  The phone proxmity area is (Norwalk).  They are supposed to be debt collectors or possibly scammer(s), be careful not to respond with any give out....valueable information, SSNs, address, phone numbers for (cell phones), or "admit to any previous debt(s), they....or the one person may ask for, instead ask them or he/she... all the questions in reverse, and especially their address, title and position, suite, bldg. # contact phones, etc.,                                                                   T.

Got this call about an hour and a half after blocking it on my cell.  Guess blocking does not work?  Appears to be a VOiP call located in the suburbs of Los Angeles, such as Bellflower, Cerritos or Downey.  I assume it's tellemarketing.

Just got a missed call from this number.
