When I search for a way to stop these calls a similar phone number came up with only the last digit different and a comment for it talked of a do not call request service. Here's the info that helped me too; I had them check this phone number to see if it was also on their list and it was so after giving them the receiving phone number a couple of days ago, the calls stopped. They can be reached at 866-246-7196 scam.
