Vehicle brokedown within a month

Bought a an Audi A3 1.4 TFSI and collected on the 14th April 2022. Already on the 14th May 2022 the engine light was on. I notified the sales rep, 3 days later the car broke down. I havent even paid my first instalment. Now 10days later, not a feedback from the dealership. I am carless. The bank wants their money. The dealership got their money
