This is the third time to receive a call from this number.  A female asking for a person that I know but do not  want to give info on.  She says she is has personal business with this person but won't give her full name.  I asked her how she got my phone number and she said it was on the information sheet.  NO WAY.  The person she is asking for does not know my phone #, lives outside the united states etc.  I beleive it may be a collection person.  CID reads Baltimore MD
