Broken nose because of weightlifter at David Lloyd Dartford

I used to be a member at David lloyd Dartford until had my face smashed in when a weight fell on me because some other member was weightlifting heavy weights and throwing them down on the floor. The vibration caused a bar to fall on my face, breaking my nose and wrist. I had my arm in plaster and couldn't train for a month or so, and yet they wouldn't even let me off of paying my membership fees even though the injury occured in their gym.
I have since decided to take legal action against them, but they are completely denying that there was ever any member that does olympic style weightlifting in their gym and that they wouldn't allow that in there. I find this ridiculous as I know of several people that have complained about this one individual because not only was he dangerous to other members with his clean and jerking weights that were right on the limits of his capabilities, but it was also very annoying because the whole place shook when he dropped them from above his head.
I believe they have since gotten rid of him, but not before he caused my injuries
I would like to hear from you if you have been to David Lloyd Dartford and can confirm that I am telling the truth about this other member because david lloyd are basically calling me a liar
