800notes is not affiliated with your callers, we are not calling you either. 800notes is a forum for reporting who calls you and any information you may have about the call to share with other forum users. It is highly doubtful that your callers are reading here also. We can't stop anyone from calling you either or remove from a list.
Maybe your phone service provider can block or provide a call blocking solution for your business.
This is for health care...if you call them back and politely ask them to remove your number from their list they will add you to their Do Not Call list.....I had received calls yesterday with no message and just tried it back a few minutes ago
