All calls originating from the 207 area code are SPOOFED. The numbers are not actual live telephone lines. If you are on the National Do Not Call Registry, file complaints for all telemarketing calls on their website www.donotcall.gov. I have also been advised to contact your local Congress Representative to encourage them to make decision on the proposed law to make such activity illegal (in all states) and able to be prosecuted. When I answer these calls, there is only dead silence and then the call disconnects. On one occasion, the person on the line tried to offer me a credit card but refused to tell me with what financial institution the offer was made from. There is never an option to press a digit to be removed from the calling list, nor can you prevent spoofed calls from recurring.
Extended Warranty message offerred , even though number is registered with DONOTCALL.GOV, I understand that company is rated "F" by BBB,org & that owner is reportedly a member of the Gotti clan. It figures he would have no respect for the law until you put him OUT of Business.
