This is already a business reality for most savvy organizations. Example, ordered pizza on saturday. Sunday, call another branch of the same pizza shop and the person answering the phone greets me by name before I even have a chance to say hello...

I was creeped out for a second, but then proceeded to order more pizza.

There's nothing weird going on there.. They took down your name when you called and they simply log you in their system with the phone # you called in with, your name, and likely your address if you got it delivered.

Information sharing is only recently the norm. Even between different branches of the same pizza chain.

I'm just saying it's not likely they used a API or something to find your name from your phone number. They are just using good ol manual registration to make your ordering time faster next time.
