The problem with filing a complaint to 'THE NATIONAL DO NOT CALL REGISTRY" will not stop any calls, as they do absolutely nothing when you complain. I have filed over 1,007 complaints to the 'DO NOT CALL LIST", and they will not do anything to alleviate this ongoing telemarketer call (among the 1006 previous filings). If you take a moment to look at your phone bill, there are 'FEDERAL AND STATE TAXES' levied each and every month (that we as taxpayers fund the 'NATIONAL DO NOT CALL REGISTRY", whether that be a land-line or cell phone. Also, note that filing a complaint will only increase the amount of telemarketers, as this 'FEDERAL AGENCY' gives out your phone numbers! This is your 'GOVERNMENT ' in action. We the people are the 'GOVERNMENT', however, Congress thinks otherwise, and creates the "NATIONAL DO NOT CALL"!
Not selling anything but I did buy a Digitone Call Blocker and for the most part it has worked well. Pretty easy to use. I have phone service through my cable company and have had no problem with it except occasional dropped calls when a blocked call comes in while I'm on the phone but the problem has been few and far between--certainly worth it to have most of the annoying calls stopped. It can block up to 89 individual numbers and entire area codes if you want. Google Digitone and it will come up. Costs about $100.
