Naomi –
Type of a scam Sweepstakes/Lottery/Prizes
Person calling himself Elon Banner called from 202-470-2040 claiming to be working with Publishers Clearing House and said my Aunt won some money so he wanted to ask her a survey. He claimed to be from North Stone Financial Group. Their website has grammar errors and speaks in very general terms about what they do, so I told my Aunt it is too fishy and that if she had won something PCH should mail her a letter.
Also note that their website claims to be BBB accredited, but I could not find them in your database.
