I know this may seem like "DUH!" but make sure you make copies of EVERYTHING pertaining to this issue....save EVERYTHING...any voice mails, emails, texts, if you speak via phone make a written record of it...date/time/length of call/incoming phone #'s....and (im more paranoid/ocd then most) but I also make a 2nd copy of everything and give it to someone I trust with my life for safe keeping.
All of this helps a lot if it ever gets to the point where lawyers/legal systems are involved.
Even if it doesnt its good to have records of all this sort of stuff...especially if your going to post up on BOI on fauna
