I have a new phone and also registered my number w/Do Not Call.gov. I get an inordinate amount of calls from the following phone numbers ( all from the same company ) asking for ( probably ) the former owner of my new phone number. I called this company XXXX times and spoke to different employees, explaining above & asking them not to call again. Apparently their employees are XXXX or incapable of removing my number. I even added my last name to my voicemail message, to no avail. ( They keep asking for a XXXX.I am not wasting any more time calling these XXXX. They most often leave hangups. ONLY other calls are automated. 
If you can help me I would appreciate it. thank you
