This person(s) are calling from a Magic Jack assigned phone number so the could literally be anywhere. Not sure how/where they got my cell # but I have since used one of the many free Call Blocker apps available for my phone and blocked their phone number permanently.
Just got a call from this number a few minutes ago. It is 4AM! The person did not say anything and after a few seconds, hung up. This is totally disturbing because when you get calls at this hour it is usually not a good thing.
