This number's carrier is Callerid4u Inc.
Call (206) 792-9399 and complain. I spoke with someone today who told me he will make sure I'm not called again (they appear to monitor) or they will cut off services for Senior Shield. Call them today!
Robocall. This is the same company that shows up on caller ID as CARD SERVICES. Message makes it sound like they already know your credit card information and are offering "your last opportunity" to lower your interest rate. I've been offered my last opportunity about 100 times in the last year.
