I don't know about this number and I don't have any debt. From what I see in the comments, I would strongly suggest you never give anyone any information unless you know them and never give out account numbers, banking information or SSN. This does sound like scamming. No reputable company would be rude and threatening..
Received third call at 11:46 a.m. CDT on 31 Jan 2015 from 1 (214) 380-2008 originating from Dallas, TX. Did not leave a voice mail with this the third call. Previously reported the number 214-380-2008 on 21 Jan 2015 for call received on 20 Jan 2015. Suspect "robo-call" that I did not answer. Received second call at 6:15 CDT on 22 Jan 2015 from 1 (214) 380-2008 originating from Dallas, TX. Did not leave a voice mail with this second call.
