Chevrolet Spark — Discrepancy in Amount I had paid and bills I have received

Address: Maharashtra

I have been cheated by Chevrolet. I had paid for a new car but they did not give me the receipts for the whole amount. Also they mentioned that they cannot disclose the charges as it is not in their policy. Moreover, they gave me wierd reasons that the amount went into bribing the RTO officials, fuel charges, driver charges etc. I need help on this and need to know what should be done so that either I can get the money back or get justice in some way or the other.
