Many communities will have something called a "Dispute Resolution Center" or "Community Resolution Center" designed for people in your situation. While I do not practice in Oregon, I did a search and found Community Mediation Services in Eugene, Oregon. The website is: http://www.communitymediationservices.com/ and its phone number is 541-344-5366.
To make the mediation efficient, I would encourage you to review the lease agreement that you have with the landlord and to examine Oregon law as it relates to tenant's rights. There may be a legal clinic or legal hot-line in the Eugene area that can provide you with the legal answer to your situation before you attend the mediation.
I hope that you found this information helpful. Good luck!
