They are "hiring" personal finance education people but don't give their company name and call random people. Seems suspicious to me.

"Sandy" called from private number and left a voicemail saying she had been referred to me from an unidentified source. Wanted to see if I would be interested in possible full or part-time money-making opportunities. Said she was in Torrance, CA.

Did not leave her last name or name of her company. BIG red flag! Did not bother calling back.

Sandy called me out of the blue, Don't know where she got my telephone number, not listed for any jobs.

Offering a full or part time job,

Must be a scammer.  Don't have my number listed for any jobs or anything else except stuff for sale at craigslist.

absolutely scam from Craigs list

Caller name was Kristine and she called to say that our business won.. and I interrupted her and said "Sorry, we aren't interested" and hung up. CLEARLY a scam caller as businesses don't "win" free things. GET A LIFE KRISTINE AND STOP SCAMMING PEOPLE!!!!
