I've been getting calls daily from this number "regarding a personal matter", I finally answered and was offered a cruise trip. They finalize by saying "in sorry, I couldn't hear you, would you like me to connect you with a rep?" I'm guessing they're attempting to make me say "yes". Saw on Facebook that they record that "yes" and use it for authenticity on purchases. Didn't respond to them.
EDIT after listening to voicemail: live caller (female) named "Lashay Kelly" (sp?) left message saying "we need to discuss an urgent matter with [my younger brother's name], please call us at 8882400182 x422 and reference file number 1428324." This happened a few years ago and I called my brother flipping out (he's been imprisoned for credit card fraud in the past so I assumed he was up to old tricks), but he denied knowledge. He has never been given my mobile phone number. Did more research then and appeared to be a scam using my actual personal info.
That 888 number doesn't bring up any hits on search.
