i just don't know who this is.

It is spam

Be careful about this number.  She is a spammer.  She was speaking very fast and not very clearly.  She called my wife and I picked up the call.  She sounded almost desperate to get me to answer some survey regarding some sweepstakes for people who had mastercard, visa, discover etc. (I am sure she covered it pretty much all, very fishy).  I told her that I know of no company that represented all those credit card service providers for a sweepstakes.  I asked her to give me her phone number and the name of aher supervisor and company and I will call her back.  She refused to give me any number and insisted that I do the survey with her. I hung up the phone.  
   These are desperate times indeed.

Yes I got a call from this number.  She said that it was regarding a sweepstakes from people who hold mastercard, visa, discover (she covered it pretty much all).  I asked her if she knew the last four digits of the card she was talking about.  She wanted me to answer some survey.  I aksed her to give me her company's phone number and her supervisor and I wil call back.  She refused and insisted that I answer some survey.  I kept the phone down.  Probably fishing for private informatio.
