They call me more than one time a day every single day. No one ever gets on the phone and if you listen and wait it will say to press 1(I think) to stop getting calls from the number. You press 1 and then it just keeps repeating that and you hit 1 and it gives you the same instructions. It's BS. Kinda like trolls on random sites with no life.
Just a thought, I had heard from friends you have to put your number on the dnc list yourself. It's not perfect but it does seem to help some. If you ask a company to do it thats silly to think they would. A legit one maybe but these scammers don't give a rat about your time or personal life. Don't count on them to remove your name and number.
I don't know how to get in touch with the DNC company or number or whatever but try finding a way to contact the source itself and put your number on it. You may be able to call utility customer service and ask them. Good luck
Waited long enough to hear someone say hello, asked to be taken off the list, they just hang up. Got another call two days later, same thing. If you wait long enough someone does talk. And if you call it back, the first option they give if you remove your number from the call list. Hope this helps someone else!
