Poor workmanship

The clutches on my car were changed in March after taking it into to Audi for slipping gears. 5 months later car towed into Audi after it had been smoking. Diagnosis discovered issue with the flywheel and they’re going to change it with the clutch again. Audi refuses to take responsibility of poor workmanship, blaming flywheel to be worn, warranty won’t pay as its ‘flywheel’ regarded as wear and tear component. Audi to replace clutch ‘again’ they say its a factory fault. The new assistant manager has been nothing but rude, would hang up phone whilst talking. 2 times had said he will get back to me and didn’t. Told me they will replace the clutch under warranty and I can take my car without replacing flywheel and do whatever I want.
