This Kaiser is the health care provider here in the bay area. I have no idea why they would want to call me. I never inquired about their services, I have health insurance elsewhere, and they did not leave a message. I suspect that they dialed a number incorrectly when they intended to call someone else.
Kaiser is a health provider. This number is their Santa Clara campus general number. Anyone calling out will use this number. It is entirely possible that the calls were accidental, most likely due to transposing a number while dialing, or the number being called was recorded incorrectly. There is no reason for them to call unsolicited. That just isn't they way they operate. I know this because everyone in my family are Kaiser health care members, and my wife also works there as a health care provider.
Some of you really need to chill out. Don't even claim that you haven't at least once called the wrong number, ever. If you have made this same mistake that we all have done, they you are just the same kind of horrid, harassing criminals that some of you claim Kaiser to be.
