just a message left - from care.com - letting you know updates to the site .. i did have a resume posted there at one time - that is how they got my number - unsure if they just call random people or not
800 notes is not affiliated with who ever is fraudulently charging your account and you need to stop this at your bank by filing fraud. I recommend filing a fraud dispute with your bank or CC holder and also filing reports with the FTC & CFB..
