Called twice now. No message left either time. Phone display says Laughlin, NV.

They called, left no message - blocked number.

I can't find this number listed for them but when I call this number back from a blocked phone the recording answers, Glass Mountain Capital. They're a collection agency with a nasty reputation for being dirty. There's a video about suing them on YouTube but I didn't watch it.

called us; left no msg.  we are on DNC list so I will block them.

I have had my phone number for four years.  If this caller is a collection agency, they have been cheated by the original lender who probably cannot contact the original borrower because they moved and changed their phone number..
