Carvana....I need a good lawyer...long story

Bought a car from Carvana in June. My trade in value was almost $5000. A Fiat 500. The rest is car payments over a couple of years. Told them right before I bought it that I would be moving back to Nevada in a couple of weeks and asked if there is a problem with registration. No, all in order they willl be issuing the registration to my Nevada address. Well here I am early November without ANY registration and Carvana is not willing or able to give me another set of temporary tags. I had two already. Estimated timeline, given to me over the phone,( I hate it that they do everything over the phone) is end of this month early next. So I have a car that I make payments on and pay insurance but can not drive. I told them on the phone that I need a car and if they can not fix is it asap then they should take the car back or buy the car back .Almost dropped out of my chair. The guys answer was they can not buy cars without them having a registration.

I am at wits end. I pay for a car plus insurance but can't drive and Carvana is just stalling. The sentence: "I am not in a decision making position", is comming out of my ears. No help from anybody just blah blah blah.

Anybody need a good lawyer for that case?
