Toyota of Hollywood Failing to honor power train warranty Hollywood Florida

First of all, I called Toyota at 800-331-4331 to speak with them about this before filing this complaint. They don't answer the line but let you leave your phone number for a callback. That was days ago. They don't call people back. I originally leased a new 2022 Camry from Toyota Hollywood. Prior to the lease ending they asked me to buy out the lease. Once I bought out the lease the car broke down. Highly unusual for a Camry with 40,000 something miles. They replaced the transmission under the warranty. Then it broke down again. This time they told me that it was due to "contaminated gas" in my tank. I had the state run tests at the last 7-11 I gassed up at, it was the only place I gassed up at in the last 6 days prior to the car breaking down again. The tests results came back negative which effectively ruled that out. Doing an online search, Toyota of Hollywood has a history of complaints regarding this, saying a problem with a car is "contaminated gas." Toyota of Hollywood is either fabricating this test results or put contaminated gas in my tank themselves. The tests show that there was no contamination at the last place I gassed up at. Toyota of Hollywood sold me a car with faulty engine problems I believe and is trying anything they can to get out of addressing the issue. And Toyota isn't calling me back about this.
