We’re sorry to hear about your experience and appreciate you bringing this to our attention. That’s not the impression we want to leave, especially after you’ve trusted us with multiple purchases over the years. Regarding the diagnostic fee, I do want to clarify that this is a standard practice across the industry. Our technicians invest time, training, and specialized equipment to accurately identify issues, and the diagnostic fee covers that labor—just as it would in any professional service. That said, we should always clearly communicate this upfront and ensure you understand exactly what you’re being charged for and why. More importantly, it sounds like we may have fallen short in explaining the results of your visit or delivering the level of service you expect and deserve. That’s something we take seriously. I’d really appreciate the opportunity to connect with you directly to better understand what happened and work toward a resolution. Please reach out to me at your convenience so we can make this right. Thank you for your feedback—we value your business and hope to earn back your trust.
