I have gotten three flyers in the mail from Viacord Cord Blood Banking in the past 2 days. Never have I Googled them, given them my address, or established any kind of contact with them. I don't know how they got my information and street address, but I would really like them to stop. They completely butchered the spelling of my name, so I know it couldn't have been pulled from one of my social media platforms. What should I do?
