I'm sorry to hear that you had a bad clan experience. However, the forums may not be used to make accusation about players or clans by name.
If you have issues with a clan that you'd like to resolve, that is best attempted by speaking to the clan leadership in-game. If you are unable to reach a satisfactory resolution, then it's best to agree to disagree and move on.
There are many excellent clans in RuneScape. I'm sure you can find one that is a better match for you
