Watch for these phone numbers....321-248-4100, 713-893-3869, 877-382-4357, 866-331-3122
All are associated with different collection agencies. Or, a few possibly connected together. These people should NEVER GET ANY INFO...and never any money either. Wether you owe or not. They HAVE to provide physical evidence of monies owed. If they do not..it is simple...you do not owe.
They CANNOT threaten you with arrest or violence or court. Trust me, they have done that with me...I am still here.
The best thing to do is ignore the calls...or do not call them back. And complain to the FTC.
