Transmission Stuck In Gear problems of the 2017 Ford Focus

I was accelerating from a stop sign when the car didn't want to go forward, the rpms just idled as the engine revved but I couldn't drive forward, then the vehicle lunges forward, as if the transmission was stuck in neutral. After it jumped forward it began making a terrible grinding noise and lost control, almost driving straight into another car. I then proceeded to pull over and turned off the car, then it made these loud clicking noises and the emergency transmission light flashed red and said �transmission overheating, stop and turn off the engine. � I left the car sit for 2 am hour, then went to turn it on and it would not start. It only made the ticking noise again. After trying to start it 3 times, it finally turned on, but continued to get stuck as the car would not move even though it was in drive. The next day I took it to the dealership but as I left my house and got on the freeway, the vehicle started rolling backwards on the inclined on-ramp even though it was in drive. Oncoming traffic swerved around my immobile car as I panicked and floored the gas petal. It finally lunged forward, seconds before a semi came barreling through the lane. I got it to the dealer as it flashed the transmission overheating light. The check engine light was on as well each time. The car had already been serviced 4 times prior to this, for transmission issues and multiple recalls. Each time I took it to get serviced, it got worse. When I finally picked it up, I couldn't even get it home because it broke down half a mile away. The dealerships service department refused to do any repairs to the vehicle even though the transmission failed and nearly killed me. They printed me the papers stating the clutch, actuators a & b, the t/o bearing, and another part need to be replaced and it will cost me $1800. In other words, I have to pay them just so I don't die in Fords faulty car.
