Carvana complaint: Problems with car

I received a from carvana about 4 month ago and for the 4 month I’ve been having nothing but problems with… The first week I got the car a sensor went bad it and started over heating (not a big problem easy fix) a couple days after that the transmission started slipping so I had it taken in again to get fix….. Took a whole month to get back didn’t even have the car a week and I’m paying for a car that ain’t even in my a whole week…. Well thought that was the end of it car was running fine for about a week and a half went to go get something to eat on my break, went into the store came out and car didn’t even want to start..I… Had it towed to dealership and now the starter went out…….. Got that fixed thinking ok that’s it I think the bad luck of this car is done, well 3 weeks later now my check engine light is on now my catalytic converter is no good and now warranty doesn’t cover it…..
