Another person described a call from this number as:
the message says "this is your final courtesy call blah blah blah lower your credit card interest rate blah blah blah before we close your file. Press 1 to talk to a service representative." Every time I press 1 and ask the rep how many of these final calls I'm going to get before they really quit calling and ask them to get my number off their list they hang up on me.
The call I received was identical with the exception that a person did answer the phone and identified the company name and his name "Frank". After this brief statement he disconnected without allowing my response. I previously received a similar call from 503-457-1836 so it is probably the same scam.
