I receive calls multiple times a day wanting me to sign up for a free medical alert device. I'm sure that if I sign up, there will be fraudulent Medicare bills. There are other scams going as well. When I call out the scam, I'm frequently told that "we should talk about it at another time." Calls come from a different number every time, and phone area codes from many states. They are hoping that one day soon I slip into dementia and fall for the scam. My phone is set to block calls from unidentified callers, but they get around that. Works best to keep my ringer silent and miss many of the calls.
