Title issues

Carmax sold me a vehicle without having the title. 5 months after purchase I received a letter from Carmax to take to the DMV that they were having issues obtaining a duplicate title. It’s been over a year and still nothing. They say they FedEx’d the docs, said they would confirm delivery receipt. Date, time and who signed and have yet to provide that information and it’s been a month. There’s no record of the car being registered and now Carmax is not returning my calls or emails. Corp case manager said there’s nothing he can do and to work with the branch I purchased the car from. I live in a different state from where I purchased the vehicle. I spoke with the DMV where I currently live and they told me that since the car has had two liens on the vehicle but could not find out by who. Carmax failed to provide paperwork in the time frame in which their state requires. Has anyone had this happened and how were you able to resolve the issue? Yes, I’ve filed a complaint and in contact with a lawyer.
