They are offering "free" vacations.  It must be a timeshare scheme or something like it.  Do not fall for this...

Just got a call from this #.  Someone, in very broken and hesitant English, said they were calling from Diamond Vacations.  There was a lot of noise in the background....either someone's home or an office setting.  I said I wasn't interested and hung up.  The only reason I answered it was because it was from the same area code as i live in (Daytona Beach area) and I thought it might be someone I know.
