Update, they called again, this time as I set up for no ring I did not realize the call came in. I am not certain as to the validity of this tidbit, but somebody told me that Indian Reservations do not necessarily have to comply to all federal laws, such as DNC lists and these calls could be coming from such a location. I checked my over 200 blocked numbers and oddly I have about 12 from this area code, of which I do not know anybody within 500 miles of MT nor do I conduct business with anybody in that area. Peace

Received phone call at 11:31 am, nobody talked, so just hung up - this has happened several times!

"Rachel, from Card Holder Services."  I added it to my Reject list.

Had a call on my caller id from a  number 406-673-5421 today. No one there. No message or nothing

I get these robocalls from credit card companies every day and always press #1. I like to see how long I can keep the person on the phone for. Give them fake details but a credit card number that is just a couple of numbers off - so it looks right but the algorithm wont work. Great fun!
