no message, caller id said "SERVICE CALL" undetermined who/what/where.

Hi, I am back with more news about this particular number-they called back within a minute after hang up for the third time. I answered this time, What the automated voice said was a blurb about a time share and if i wasn't interested then a rental unit. I didn't say anything just hung up. These folks are scammers is what so ignore them, report them and don't let them hassle.you.
