14.1 Process. If you have any concern or dispute, you agree to first try to resolve the dispute informally by contacting us. If a dispute is not resolved within 30 days of receipt by us, any resulting legal actions must be resolved through final and binding arbitration, including any question of whether arbitration is required, except that you may assert claims in small claims court if your claims qualify.
