Supposed call from Dun and Bradstreet.  "Hi, this is James over at Dun and Bradstreet. My number is 866-257-4284 ext. 2922. I'm calling in regards to the business' commercial credit report. Please give me a call back as soon as you can. Thanks."

Since there several scam type calls that are ostensibly from D&B going around, we will block this number and the 866 number.  We don't use D&B services, nor do our clients.
