I have a guy who actually owns his own company dealing with these types of situations... if you would like I can pass along his information to you and maybe he can give you some true legal advice... He's dealt with Evicitions, Court Summons, etc and he even had his own apartment buildings where he dealt with being a landlord himself.
Let me know if you'd like his information or if you would like your info passed along to him. PM me or not (if its been resolved).
Good Luck to you. I've been in that situation recently and my friend was a BIG help.
Just talked to my friend he said that the Residential Tenancy Dispute Resolution Service is more tenant friendly and is cheaper but if you feel that the person helping you there is not "intelligent" enough regarding your case that you can go thru him but he does cost more... but theres a lesser chance of you losing the case.
hope you win, because i hate landlords like this... i've just been thru dealing with poor landlording as well. I wish you all the best.
