Ford Escape just bought and goes bad right away

Bought this Escape from a Chevy dealership. Drove it one hour transmission light came on.. They put me off and put me of as I talked to many about it.. Now it's been four weeks and transmission doesn't go an I have nothing else to drive... It's my problem now.. They said I could trade it for some cheap vehicle and $2163.00 to get into another one of there vehicles. Sad part my girlfriend was going to buy a 2017 or 2020 Chevy pickup Saturday she backed out because of what happened to me. She doesn't want it to happen to her...
