Called but did not leave a message

CID:Kfj Marketing

No message.

I've never heard of them, so I blocked them with CallClerk.

Received a call but they did not leave a message.

When I called back the automated attendant wouldn't identify the company up front.

I answered, they hung up. Automated response when I tried calling back. There was an option to be added to their do not call list.

I didn't recognize the phone number so I declined the call. There was no message left. When I called it back, the automated recording did not identify the organization but offered to let me speak with an operator, leave a message, or put my number on the Do-Not-Call list. I found out the company is apparently "KFJ Marketing" by Googling the number.
