The Omaha-based Better Business Bureau is warning people about suspicious phone calls regarding medical alert devices.

The BBB says consumers from across its service area have inquired about the calls. The people report that the callers say medical alert devices have been purchased for the people but the callers need more information about the recipients for delivery.

The BBB says it made return calls and was told by one person who answered that the alarm devices carried a fee of almost $35.

BBB President Jim Hegarty says the calls to consumers were “very suspicious due to the secretive nature and lack of full disclosure to their real purpose.”

The Omaha-based BBB service area includes Nebraska and southwest Iowa.
