tring to find out what and who owns this number i think its a scam

like to report this as a scam and how do i block them never heard of this place or people

Debt collector wanting personal information before they will tell me what the call is about.  Do they think I am so stupid as to give them any information personal or otherwise. I told them if they want to contact me the to do so by mail, they had the audacity to ask me for my mailing address.  If I owe you a bill you should have my full name, address, phone number etc., if you don't, Oh Well!

I have a PST phone number but I live on CST.  They called me at 10PM.

Called, no message left, just block #
