Rec'd robocall message with "Sylvia" claiming to be my personal jeweler from San Mamo Jewelers, or something like that.  Message goes on to say that it's time to bring my jewelery in for cleaning , and that they're the place for all my jewelery needs, etc.  Then gives hours of operation.  Caller Id displays "Marcus Diamonds", but name given of actual jeweler is San or Sam Mamo's Jewelers.  Confusing? , so I'm a little suspicious. ( But could be a legitimate jeweler.)
