I called back. The answer says to call back some other time, or you may leave a detailed message with your name, phone, number, and desire to be taken of their list.
Ask your phone company if call blocking is available and if it is are you able to block ALL unwanted calls or just selected ones? OR you can purchase a Panasonic phone that will block up to 250 numbers. It is well worth the price. I'm working on over 100 numbers already from scams or telemarketing calls.
This number is active again. No idea if it is the same crooks who used it two years ago as reported above. It rang once at 2:23 pm today and was stopped by my blocking service.
