Who called from 7206398020

Two recent calls we didn't answer, both late evening. Left no message, blocked.

They seem to prefer calling Sat evenings, Sunday mornings, or other "family" times.

Received calls from 720-639-8020 Friday, Saturday and again today.  They never leave a message.  I will NOT ANSWER CALLS FROM NUMBERS I DO NOT RECOGNIZE.  If it is important, leave a message.  As for "call type" - Annoying to harassment.  Want it to stop!!!!

They call several times per week including on Sunday and never leave a message indicating they are nothing more than SCAM / SCUM.

Unrecognized number. Blocked for the future. Caller ID says "Contact Center ".
