Business plagerism on facebook?

[Phoenix]

I wrote an article for my stores facebook page which has been plagerised by our competitors on their facebook page with no credit given to me. I know facebook is notorious for copyright and privacy issues and I probably can't do anything about it but just in case I thought I would ask. As it is one business stealing content from another, do I have any legal rights considering they are passing it off as if they wrote it? Just in case it makes a difference regarding laws, this is in Scotland.
