New XPS laptop came with another's ID

I ordered a 15" XPS laptop on 12-18-17. It came and after it booted up, another person's ID was on the sign in page. It also wanted me to try authentication for this "John Doe" person. The email was also listed, so I contacted the fellow. He had a Dell laptop several years ago, claims he sent it in for repair but never got it back. Dell tech came out to switch out the hard drive. After that HD switch I am still getting "John Doe"'s ID on my sign in area and authentication. I have obviously not put in any of my data. Now awaiting their next move. Anyone ever have this happen?  Thanks.
