NASHVILLE (AP) — Officials are warning Tennessee's seniors about a scam involving recorded phone calls promising free or low cost personal emergency or medical alert systems.

Tennessee Commission on Aging and Disability Executive Director Jim Shulman says seniors and people with disabilities have been receiving phone calls that say they are recipients of free emergency and medical alert services.

The message says someone has ordered this system for the caller and the call is to confirm shipping instructions. The listener is told to press a button to speak to a customer service representative.

Pressing the button connects the listener to someone who asks for credit card and personal information.

Shulman says credit card or other sensitive information should never be given out over the phone to an unknown person.
