Who called from 7403400057

No message left. Called them back and only given an option to press 1 to be placed on a DO NOT CALL list.  Company is not identified. Since I'm already on the Federal Do Not Call list and they are ignoring it I just hung up.  Most likely some form of scam.

Received call to my cell phone, answered and was disconnected.

Three separate calls one after another. left no message

Claimed to represent Capital One Credit and wanted to lower my rate. When asked a couple questions, they hung up.

Recording only.  No live voice.  Concern with lowering credit card interest rate.  Asked to push 1 or 2 I just hung up.
