Lower rate on Visa and MC

I just got a spam automated call, pressed 9 to get operator, asked over her sales spiel, were did you get this number, she told me to have a good day and hung up. I wish I had CallerID, I would so look up the number in Google, bet you others have had this experience too. Not the first time they called, but I do hope it is the last or I will prosecute them. My neighbor wants one of my new phones only because he is sick of telemarketing calls.
