Wordpress hijacked my website

#1

I was going to try wordpress, so I let it install. After looking at it, I decided it was too difficult to figure out, but now when I try to go to my website firstaidnow.net it is a wordpress site and not my site,

How do I get my authorization number for my domain name which I own? I am going to a different hosting site.

Just change your nameservers to your other provider

how do I do that? I am not real savvy about this stuff, however I am usually pretty tech savvy, so I’m not a complete idiot.

With whom did you register your domain?
