It may not be a scam, but when you're told to stop calling, you have to stop! Otherwise, per 653m of the California Penal Code, it is telephone harassment and can be prosecuted criminally. Also, UCLA and Westat can be sued civilly for continuing the harassment after being told to stop!
I screen my calls on landline and cells lol you are never going to get me and you call 7 days a week.Whatever con game you are playing GET A JOB!!!!!!!
