Can't be a bill collector if they're calling me. I have no outstanding debts. Home is paid for. Car and truck are paid for. Balance on the only credit card I have is zero, and I have no loans. Nope....not a bill collector.
Only legitimate businesses pay attention to the DNC list. Scammers, spammers, and phishers could care less about it. I actually removed my number from the list and the calls diminished.
