Who I have the same questioned this topic

I sent this emailtoday to my congressman

Dear Congressman Morelle
Something need to done to control and reduce nuisance phone calls. Recently the number of unwanted phone calls to our cell phones has increased dramatically. Both my wife and my phone numbers are listed with the do not call list but this has resulted in no reduction in calls. We receive 12 or more call per day from unknown numbers. We do not answer the calls. I complained to Verizon and they offered a blocking program for our phones that would cost $2.99 monthly. If telecommunication companies have effective programs to eliminate this illegal practice .they should be required to offer them free to their customers. The illegal practice of junk phone calls is reducing the efficiency of the nations communication network.
Thanks for your consideration of this issue. Maurice
