Accident Damaged useless car - Bad Business acumen

I purchased a Vehicle from Lisabank last year September, only to realize a month later that it was a raw deal. The vehicle started giving me issues on the second month of owning it. I spoke to Angelique their General Manager, who does not care about Consumer rights at all. The car was send back to the dealer as it had a bad knock everytime you turned, who returned it a few days later and said it was fine. Took it to VW who checked and confirmed the car was in a collusion and new wiring was done on the vehicle, respray etc. This was raised with Mrs Bells who again fobbed me off. Car nearly killed me when the brakes missed which was because of the damaged suspension. I then asked them if there is a way i can get out of the deal, which was not an option according to them. I was then advised to try and trade the car in, which i now owned for 3 months. I declined the deal as it required another deposit from me. 1 and a Half month Later i am sitting without a car which has broken again. And again i have tried to escalate with their general Manager who simply does not care. The car is now with Dean who is a repairer for Lisa Bank- A company owned by his dad. This company is BAD
