Scam preying on the elderly. They're trying to sell medical alert devices to the unsuspecting and are happy to just take your credit card numbers and names. Buy your medical alert devices from a reputable dealer, not from these parasites. Caller ID is "Alert".
Called five minutes ago, stated "don't hang up, this is not a sales call, important from message from AARP". Hung up the phone before they could go any further.
