I used a pay service to get background on the number. This is interesting:
Name: Lucy Murphy
4837 Bass Pl SE
Washington, DC 20019
Phone Type: Land Line
Carrier: Nationsline District Of Columbia Inc - Dc
County: District of Columbia
Average Income: $27,317
Average Home Value: $96,300
Now, if you call 202-367-9284, you don't get Lucy Murphy -- unless she's the person who is recorded saying "For quality purposes, the call may be recorded..."
The real question is, how to document this subterfuge in a way that will convince, say, your local senator, that Credit One needs to be kicked in the balls. With creditors who don't mask their identity, you can provide your phone records as proof that they've called you 12 times a day for 6 months. In a case like this, it's way more complicated.
My wife and I are journalists - she in particular has investigative experience and substantial knowledge of the banking industry. So we're on it. Cross your fingers...
