Caller ask to speak to my 17 year daughter.  They will not explain why they want to talk to her or who they are.  The will not identify themselves.  When you call them back from a different phone number you receive an automated message that the number is not registered and to enter another registered number.  When you provide the number the originally called an live person picks up and ask is this....(my daughter's name)?  When I ask why they are harassing my 17 year daughter they then say they will delete the number from their system.  Two days later they call again.  This time I pretended to be my daughter but they tell me I am not her because they know her voice.  When I say "What do you mean that I am not her?  They say they will call back in 20 minutes.
