I have been getting calls on my cellphone from this number for literally months.  They always ask for the same person, "Shaneka" or something like that.  Initially, I was nice, told them they had the wrong number, verified my # the fact that it is a cell how long I've had it, etc.  It has made no difference, they continue to call.  One of the first calls they identified themselves as a bank or mortgage company, I don't remember which one though, they no longer identify themselves, just keep asking for this person.
