Grievances Ignored in Tennessee

I am writing this letter in hopes that you can provide me with information on how to combat a unjust prison's grievance process. As of the moment the grievance process at MCCX is broken and I and other inmates really have no way to have our complaints heard and addressed. The grievances go unanswered most of the time and/or the process is purposely delayed to let the time-frame expire after which the grievance is denied. The grievance chairperson is supposed to pick up the grievances daily but if and when she does pick them up and process them, she uses this as a reason to throw the grievance out. If I knew any better, I'd say this is illegal, but I'm really not sure. I have brought this issue up to the warden but it seems he is in cahoots as well. Can you please send me some info about how to combat this issue and hopefully fix it?
