This is the reason I use Google Voice instead of giving out my actual number to anyone other than my immediate family members. This company has been calling early each morning for several days from (404) 410-7486, leaving no message.
If you are also tired of people who violate the DNC list. Here's what you can do:
1) Get a GoogleVoice number.
2) Set up a contact called "solicitors".
3) Switch the settings to "blocked" for your contact called "Solicitors".
4) Continue adding numbers to that contact any time a solicitor calls. They will receive the standard "not in service" recording all phone companies use. You will no longer receive calls from that number or any number you add to that contact.
