Need help with forum deletion

Hello, I have tried to delete my old forum that has been sitting empty for at least over a year now. I would set it in maintenance  mode and delete everything. Only issue is I no longer have access to my forum anymore.
One of my old staff members removed me and re-named my forums and disabled registering rendering my entire forum useless, and would wish to have it deleted. I left it be for over a year and its still here. Please can it be removed or something. Its ruining my communities reputation.
