Good Afternoon. Though I'm glad to hear about the resolution, we did speak to parties involved to make sure direct contact with a manager and customer will be established sooner to make sure the resolution is done at a faster rate. I am glad to hear we replaced your tire at no charge when you noticed an issue after pickup. We apricate your business.
