Carvana complaint: Transmission issues 4 months after Carvana purchase

II purchased a 2014 Mercedes Benz in Nov 2021 with 40,000 miles.
In early March 2022 (7,000 miles later, four months later), the vehicle became inoperable and due to staffing shortages had to sit at Mercedes Benz for almost three weeks, leaving me no choice but to pay for a rental in order to commute back and forth to work.

Once the issue was raised to Carvana complaints through Customer Service(with an invoice from Mercedes Benz with details of the transmission issue). I was told they would only replace the car, not reimburse me for repairs. This was told to me after I paid to have for the repairs to be done (although Carvana was looped in from the beginning) in an attempt to get the car back I pay the bank note on every month.

I am a recent widow after Covid, and this is really not what I needed trying to find my balance and learn to survive on my own with my children. This is the setback of all setbacks and Carvana; a multimillion dollar company has done nothing as of yet to help me, and then when I try to help myself, use it as an excuse not to step in.

Please help as my job and livelihood are at stake here.

All the best,
