I had sent an email to the corporate office of a big company about my experience at one of their stores and about one of their employees. I had to leave my information (name, address, #) and just wanted to know if the employee will see all that info about me. I’m pretty sure they can’t but I’m curious. I don’t want this guy showing up at my door.

They shouldnt see your personal information. The company usually just uses it so they can respond to you.
