Carvana complaint: Have not received my car back from Carvana.

Received and took car in for inspection on the first day. To my surprise the car didn’t pass the inspection due to all tires bald in correct size, wheel alignment and exhaust system not good.

I called Carvana to inform them I didn’t want the car and I wanted my trade back as soon as possible. They stated my car would be returned back to me within a week but it never came. I called Carvana about the issue and they gave me the run around stating my car had been moved and they were trying to track where it was to have it shipped back to me. They stated it was coming a week later but again it never came. I continue to call the company and they keep stating my car will be sent to me. But I still have not received my car back. I am so worried they may have sold my car and I may never get it back. This has been the worst car buying experience I have ever had.
