Carmax has little to no customer service. I bought a 2016 silverado 1500 8 months ago, the truck came with special lug nuts but no key to remove them. They did not disclose that to me. I immediately tried to contact them and have yet to receive a response. I have left 7 messages and talked to the business office multiple times. I keep being transferred to the same place to leave another message with no call back. Again I was supposed to get a call back, but here I am having to call again
