The new scam is the calls are coming from your local exchange number with an automated call at first. I wait and say F & C which do you prefer? Please have your 16 digit credit card number handy. Only 2 so far have actually asked what the letters mean and when I told them one still didn't understand. The other called me disgusting. Use you imagination for the letters is all I will say Hey you called and are trying to solicit me!
