I get tons of calls a week from these type of numbers every week. The best thing you can do is to report them every time they call and not answer their calls. It keeps your number in their system if you don't answer and never do they lose interest.
Here is a good example of a U.S. “company” that illegally sold phone numbers to an "third world" age cream shill. Most of the complaints here are from women. You may have all been targeted by the same mall shop.
[***] from nuscience will not stop calling me. I asked to be taken off of their call list and they said no. I asked to speak to a supervisor and she asked why? I called back multiple times and they told me to expect many more calls and laughed. Screw these guys calling me late and waking up my children. I keep my phone on for important calls from my parents or work. This should not be an issue. I'm sure they have a whole list of people to bother. Why no respect? Because they are in another country and hate Americans. I would never buy from this company with the rude people that they hire to do their dirty work!!! Hire Americans if you are an American company!
I had a similar experience. I asked to be put on the do not call list and a woman named Theresa Lisby claimed that I will not be put on that list and that I will be getting even more calls. She said she was calling from NuSkin's call center in LA but yet it was a New York area code that appeared on the caller id. Asked to speak to a Manager and she claimed he was not available. I told her I did not mind holding for the manager but she hung up on me.
