Note: if anyone thinks I should at least re-phrase the title and the article, I'm more than happy to do that. My concern is: why do they mention UK leaving EU if I'm not UK citizen? And why there is no way to appeal/complain directly with them? Mistakes can happen from anyone, but if they don't let me contact them I have no way of fixing this.
(happy to dig up some legal documents by Allen and Overy a well-known law firm if people want to read an analysis).
