I don't answer calls from area codes or business where I have no business, much less I press any button or request to be erased from the list. That just tells this scum that the number is "alive" and you won't get them off your back. I think the best thing is not to answer and report them.
Got a call from this number. Robocall saying that their records show I am not on the google listing or something like that. I get these calls all the time, not sure if from the same number, but it is very very annoying. Why can't these people be arrested for harassment?
a zillion calls, for months, from multiple numbers, all with the same BS scam to "update my google listing". I can't begin to count the number of times I have "opted out" through the automated service, all to no avail. If I could find the owner of the company making these calls, I would fly to wherever they are, and crap on their desk. Twice. And no, I did not mean rap.
I don't know if these are the people that keep calling but if it is them then reporting them will do no good. It seems that they are London based. So far that year, 25 calls, all from a robo caller.
