Unresolved Query

I bought a car from Auto pe digree, Florida Glen last August, and I was a first time buyer, I did ask if the car is in good condition and they say I must trust them they only sell cars that are in good condition, I find out that the battery is not in good condition after 2months from the date I bought it, I immediately tell the sales consultant who assisted me, since last year there is no solution that he is giving me until todate when i call and my call and the emails are ignored. I took the car for service last month and i was told to replace the battery and again I call the sales consultant and tell him about the same thing I have been telling him from last year. How can they sell a car wich is not in good condition to a first time buyer and expect a buyer to pay the instalment and to fix the damages that comes with the car at the same time. If the sales consult wrote down that I have to buy battery in two months as a first time buyer i was not going to take it. The other thing they are debiting money for scratches and dent, but when I call to claim they ignored me, I again tell the sales consultant to cancel money for scratches and dent since there is no help and I was told to tell the bank to cancel it, when I call the bank I was told that Autopedigree must cancel it because they are the one arranged it with me. So I dont know who to contact regarding all above.
