Hi this Amit from calicut here 25 days before i booked a

Hi, this Amit from calicut here.. 25 days before i booked a i20 diesel magna , 6+1 speed euro 4 car and i have given advance of 50000 by the time of booking.. Today i got a call from my dealer and they told me that euro 4 car is not available only euro 3 is available. In the booking time itself i specifically mentioned that i need 6 speed euro 4 model. So i wanna know that is i20 euro 4 model available in the market or not ? If it available how many days i have to wail after booking..I feel like my dealer is playing wit me..
