My Android phone identifies the caller as "Corey Austin" (thank you, Google), but there was no message left. Other sites are identifying this as a spam call for a lower interest rate on credit cards. (See the White Pages reverse number search.)
This number calls every so often and they want to lower your interest rates and never leaves a message. I'm sick of them calling, I NEVER answer that number now!
They said" your CC was available for a interest reduction". Would not state who or what company they worked for. Hung up on me when I questioned them. It is a scam.
