The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the pany which produces the program, Retriever. In the latest version, people can add a spoken message.
