Said they were with Dunn & Bradstreet, and that our profile was incomplete. Being the person who acquired our D&B number, I asked "what is incomplete?" He said "the date you were established, and your payment history with other companies." We are a non-profit, and I know that I entered our date of incorporation when I established the account. So, I told the caller "I can sign in and add the payment information." That's when he let me know - "adding payment information is a PAID SERVICE." Hung up and blocked.
