Have been receiving calls from this number and others for weeks multiple times a day. Caller id says "American Express" or "Midvale, UT" This is the message they leave every time--- "This is not the telemarketing sales call. We are calling you to discuss an important matter. Please return our call at 1-800-592-1160 and 888-819-2135. We will be available Monday through Friday from 7am or 8am until Midnight, Saturday from 8am until 6:30pm and Sunday from 10am until 8:30pm Eastern Time." (the two different call back numbers and times are from 2 different messages)- I have gotten calls from this number and the following all claiming to be "American Express" 801-945-9060, 801-945-9236, 801-945-9052, 801-945-9062, 623-492-8976, 623-492-8037,866-884-0976, 888-819-2135

No one was on the phone call when I answered. It's a dead air call.
