fyi - When you call these jerks back, you have just made it okay for them to hound you forever. All they need is that ONE call from you (even if they say it's to get off their call list). Then they can claim you have a previous business relationship, because they now have a record of YOU calling THEM. Duh.
At 11;12 AM my phone system received a call from 914-436-6232 which the Caller ID received as NAME UNKNOWN. Since we were not home, we did not answer. No message was left by the caller.
Unfortunately, AT&T has no way available to its customers to block 'Out of State' anonymous calls. We constantly receive 'Robo Calls' even though we have been on the National Do Not Call List since its inception, and have renewed its coverage. Florida just started a free Do Not Call List, and it is illegal for almost everybody to violate the 'Robo Call' calls. Politicians, chariities and a few others are permitted to use them. Additionally, anyone that you have previously done business with can legally call you with a 'Robo Call', even though you have not dealt with them in years.
