Please stop answering calls from unknown people. People who answer these calls keep these people in business. When you answer they also sell your number to other criminal out fits saying this is a sucker who answer these calls and a potential victim. Stop the calls by stop answering them. Thanks for your help.
Seriously people. Stop answering calls if you don't know the number. The more calls you answer, the more your phone number will be listed in a "black market" phone database where thousands of phone scammers have access to your number. No thank you.
