In an effort to stop these annoying calls, I searched and found a do not call request service at
. They said they provide this service to a small number of clients that want to minimize complaints and save time not calling people who don't want to be called. I needed the relief of the constant calls so I gave them the caller's phone number which they verified on their list and then added my receiving phone number to the do not calls list. You need to allow 1-2 business days to process but it was well worth it as this was an effective way to stop the calls.
