I too have received many phone calls from this number. A message is never left and when I tried to return the call I only got a voice machine. One time a call came and I answered it, there was an immediate hang up.
This is about the 40th time that they have called me from this phone number. I am almost positive its that Esta Sol travel scam that has been hounding me relentlessly for almost three years. They used to call from a Nebraska area code and now they are apparently calling from Montana. These jerks need to get a clue that I am wise to their stupid scam and I will NEVER answer their phone call EVER.
Go to www.donotcall.gov and register your phone number on the DO NOT CALL list. After it is registered for 31 days, you can file a complaint if they keep calling and harassing you.
My husband recently died and left behind some significant medical debt that I thought I had paid off....I assumed this was just another collection agent....but after reading this, I know it is BS. Thanks....we are from Montana, so the 406 area code was not unusual.
