the call came on a sunday morning , at 11:35:42 CST . It was a robo sales call from a SS "associated" contractor called NTI . the robo caller left a voice mail saying Hi , we just invaded your privacy and committed a federal offense by calling you at your private unlisted number , but since we did , we're inviting you come to our web site and " bulls*t , bullsh*t , bullsh*t .... blah , blah , blah ... etc , etc , etc " . fortunately my new android call blocking app is able to determine if these calls are from the a*s wipe robo callers and or their machines . and blocked it . i does inform you tho what number just tried to invade your privacy , logs it and you can then determine if you want to make a retaliatory call , which we all know they will ignore, and sell your number for profit again and again , or just enjoy the fact that you just beat them at their own game . its easily configurable by anyone who has an android based cell phone , to block them permanently , by either using your own internal phones contact list , or use its features . or you can choose many variations of it . it is free , but as all are , the best features are not fully available . this one is called Call Control Pro , Powered by EveryCall.us . it costs a onetime only 1.99 to unlock , but if you are as pi**ed off as i am after putting your name on every conceivable federal state and any other DO NOT CALL list , since they became law .... and STILL getting these calls , i assure you this will be one of the best 2 bucks you ever spent . and i guarantee that once you install it and become familiar with its options and configurations , you will never be bothered by these pricks again . I emailed the EveryCall.us contact and told them it if they would just modify one feature a bit it would be perfectly flawless . and thanked them for designing it , and was informed the very thing i was asking them to modify was already being done and for the people who pay the 1.99 the feature would automatically be downloaded in a upcoming existing version update at no charge . and would be integrated into the next ' official ' version release . I highly recommend you get the app . and no i don't work for them and am not related to anyone in their company , and am not being coerced or paid to post this comment .
