I received two calls from this caller, each with a different telephone number originating in southeastern Michigan, within the space of about 4 minutes.  I suspect this was intended to be a phone fraud as I have had other calls from the same area insisting that they are Publisher's Clearinghouse and need me to send a check so that they can send me a package, and those calls have had callers with a similar initial script and Caribbean accent.  This caller initially contacted me from phone number 313-818-9292.  He became abusive when I asked who he was calling for (he kept saying he wanted to speak to the owner of the phone), eventually telling me I could f**k myself and hanging up on me.  The same caller then contacted me from this number and swore at me again when I asked what he was calling about because he was interrupting the school day.  Doesn't this idiot understand that if he wants to con people, he at least needs to cultivate a modicum of charm?
