Here's a copy/paste of another comment that helped me to stop the calls; You said it, this is getting so annoying I decided to put some effort into figuring out how to get rid of these calls. I found a service at 866-246-7196 that all you have to do is give the caller's and receiving phone numbers. They verify if the caller's phone number is a part of their service and add the receiving phone number to the do not call list. Allow 1-2 business days to process and then the calls stopped for me.
