There is NO need to call anyone...especially someone that doesn't belong calling you to begin with. Don't let the scasmmers like the one that posted just above this one fool you. He's trying to harvest numbers and then will try to say that you called them first.
Anyone who wants a fast and efficient way to stop the calls, call 877-646-7319, they will remove your phone number from the callers list, no other purpose. They don't want to call someone who doesn't want to be called. They want to save the caller their time/effort and you get to stop your phone calls. I called last week but didn't post this until the processing time was done to see if it worked, and it does.
If you don't pickup the phone call, their auto dialer will most likely call back again later. In order to not receive anymore calls, you simply need to follow the prompts to remove your phone number from the callers list while on the original phone call or call back the caller's phone number. If that doesn't work for you after 2 business days of your request not to be called and/or if you'd like to speak to a live person call 307-223-0458 or 877-646-7319. I did it and it worked.
