You said it yourself - they're scum bags. The DNC does work, with legitimate companies, but it's not a call blocker so it can't keep scam artists from calling you. Only you can do that. Invest in a real call blocker or at the very least, don't answer calls from numbers you don't recognize.
daily calls at 0730 and at 12nn. I work nights and the calls interrupt my time for sleep. I called the number back and used the automated prompt to remove my number from their calling list. The solicitation calls persist; a messages never left only voice mail. Today I followed the automated prompts and spoke directly to an operator with a clear request to have my # removed from the caller list. The person I spoke with was rude and defensive but agreed to follow thru with my request. If calls continue i will consider this a form of harassment.
I was being called a few times a day. I called number back...it will allow you the option to be removed from the call list without having to speak to a person. This is for a college degree.I hope this helps ugg
