Koons White Marsh Chevrolet responded

Thank you for sharing your feedback about your recent visit. I'm glad to hear you felt the service itself was handled efficiently, and I also understand your disappointment that the interior and carpets were not cleaned as you expected given the overall cost. I'd appreciate the chance to talk with you directly about your visit and your expectations for future service, so please feel free to reach out to me. Best, Christian Stark Customer Relations Manager christian.stark@koons.com 443-421-0433
