I have booked a car in Kalyani motors Bannerghatta by paying booking amount, because of some reason I had cancelled the booking and informed to refund the amount, yet more than 2months they asking sumbit receipt cheque etc even all submission I didn't received any money who will responsibility for this,
If i call sales executive, manager will not co-operate to him for refund now he is ready but account department manager not ready,
While taking money with me they were treated like king, now to refund they won't respond at all
