Who called from 3023988513

A "Valerie Jackson" left a message for me to call her at 302-398-8513 saying she is with "Stevens & James" whoever they are...

Solicitation call from a company that tries to sign businesses up for collections.

they called here asking for the owner of the company by name.  Since he rarely comes into the office I asked to leave a message for him.  Her name is Darlene James, and she's with Stephens and James

Received Voice Mail from a "Darlene Jackson" telling me to all her at the number...  Company was Stevens and James this time...  The Caller Id was "Nina Grimes"

Received a call from 302-398-8513 Stevens and James asked for a return call business type??
call back for what?
