@Babasheep,
You can always write a "poor" but fair review. Do not say anything that is incorrect, but provide facts to support your review, it will hold more water to those reading and not appear as if you are just a crazy that writes bad reviews.
You can say something along the lines after paying 200 pounds, and expecting an inclusive and safe environment to game play, I had the opposite experience. I have had death threats and bullying --- and here I would quote what was exactly said; hopefully you have it saved or take a screen shot so you do have the evidence. Then state the actions you took, so I reached out for a refund as it was not as I expected and this is the response I received --- again copy and paste their response.
You may not get your money back, but at least you can help other people from falling in their trap.
I just warn you to stick to the facts only.
