Got 6 calls from this number.  Heavy accented moron claiming in order to avoid prison, I had to call him back immediately.  Said that a US Magistrate was going to send me to prison.  If these idiots are going to try to scam Americans, at least learn the language.  In foreign countries that use proper British terms, a magistrate would be good, here in in the USA it would be an Attorney General or Federal Prosecutor.  I  like to call them back and play along and finally tell them that their mother is at my house doing something to my dog.
