I got a call from this number today. I forwarded them to my voicemail. The guy addressed himself, but not with who he was representing and said it was "urgent" that I return the call. He then provided his "direct extension" which was an 866 number, but the last four digits weren't clear and he only gave the number once. Guess it wasn't too "urgent seeing that they have only attempted to call once today...
In clear defiance of current law, this individual whom I can only assume is a debt collector declines to introduce his company or explain the reason for his call. He states that it is 'urgent' that I return his call and blurts out a number so quickly that the numbers slur together, then he hangs up. This was the second time that I have received a call from this number and the calls have been roughly a week apart.
