I hired an Oregon attorney. I was unhappy with the lawyer's services, so I wrote a letter requesting a refund. The lawyer responded by letter agreeing to refund $3,500. I accepted the offer in writing and relied on it at an attorney fee hearing by testifying that my lawyer had reduced her fees. I received an attorney fee award based on the reduced amount. Now the lawyer refuses to provide the refund unless I agree to additional terms and conditions that were not included in the original agreement and to which I don't agree. I filed a Bar complaint. The Bar dismissed it explaining it doesn't handle fee disputes. I filed a complaint with the Better Business Bureau. It's pending. Meanwhile, the lawyer stonewalls. Are arbitration and small claims my only remaining options? If so, which is preferable given the circumstances?
