New spoofed number, robo call. Telemarketing firm most likely either a contractor or a solar energy company calling. When you call back you get a prompt to press any digit on your phone to be removed from the list. Of course we all know that doesn't work and that you are simply telling the computer that this is a good phone number calling back. I've just added to the list of phone numbers I don't answer to. Glad to see the Feds and the DNC list is working. LOL
Depending on my mood and how convenient it is for me to counter-harass these continually annoying people at 424-220-6074 AND OTHER RELATED NUMBERS, I sometimes play along to the end of their game and ask them their building address JUST before I pretend to get ready to give them my credit card # --- if they give me a legitimate business address, I say I'll look them up before I pay the $35.99 monthly monitoring fee for the "FREE General Electric wireless home security system with a medical alert button. . . ." Usually that is enough to call their bluff. The line usually goes dead, or the rep makes a lame promise to remove my number. After years of being annoyed by these scammers, I have many, many times, pressed #s to be removed, re-applied to DNC, asked reps to kindly remove me, all to no avail. IF convenient I will continue to waste their time until my number is removed legitimately, if that's at all possible with their robo-call numbering methods. Sometimes its sad to hear their pathetic voices. Sometimes these illegal robo-call #s connect you to legitimate security installation companies who feed off these illegal operations connected to #s like 424-220-6074. General Electric, United-Technologies in Hartford Connecticut, knows this and claims they have legal teams working on the problem.
