I just got this call - he was asking for my ex-husband (who never had this number because it's paid for by my employer).  When I told him there was no one by that name and that it was a business line he got VERY indignant and said "this IS business and you don't own that business" and hung up.  Tried to call the number back but it says the number is not in service.

When I received this call, it was some guy looking to talk to my grandmother. I asked him if this regarded her car warranty and "Bob" (that was his name) said yes. I told him that she took care of it and, as a result, I got a busy signal. Another car warranty scam. Ignore it.

This number called me today. DigiTone blocked the call as it was not white-listed.
