Gotham Steel Gotham Steel is not Secure Internet

I like the pan. I really do. Shortly (3 weeks) after receiving it, I'm getting an email every other day that looks exactly like the below, sent from billing@autobillpayer.com:
=============
Subject: GOTHAM STEEL COOKWAR - File # xxxxxxxx (obscured for privacy just in case)
Body:
Dear xxxxxxxx xxxxxxxx,
Please call 8664414731 regarding the GOTHAM STEEL COOKWAR  you received on 05/27/2018.  This is a toll free number for your convenience as this e-mail domain does not accept response e-mails.  Your file number is xxxxxxxx.
Sincerely,
Billing Department

The number seems to go to some place who don't identify themselves, just says "Thank you for calling, we are closed. Please call back during our normal business hours of 8 am to 9 pm."
Uh, it's 7 pm eastern right now when I called. I tried to find the number, and I found a BBB Report for AB ROCKET listing this number.
My bottom line is: Gotham Steel is NOT secure. My information, including my name, has been stolen or sold to some hackers. The email looks like a Nigerian bank scam. It isn't legit. The email address isn't them, obviously. But they have my full name. The "File Number" they reference isn't anything to do with my order number.
Second Bottom Line: DO NOT DO BUSINESS WITH THIS COMPANY IF YOU VALUE YOUR SECURITY.
