i got a call from this number. ID said Tiffanay Roland

Got a call from 402-575-8818 at 11:02pm last night.  20 minutes later, my husband got a call from the same number on HIS cell phone.  No message was left and I didn't call it back.

I just got  a call from this number. Id also said Tiffanay Roland. All the guy said was "hello", "Hello" then hung up. Has anyone called them back? Should I be worried? Is something Illegal going on?

May 11th, 2009, 11:54am cell phone rang. I didnt recongize the area code or number so I let it go to voicemail. Female who identified herself as Christian said she had my resume and was with American Income.  She wanted me to call her back at 503-866-1917.  Did a little digging via Google on this number and company.  All my research indicates this is a scam derived from employment sites.
