Maruti Suzuki India — Delay in the delivery of CIAZ

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I had booked a grey zeta model ciaz hybrid on 7th of may at vipul nexa sector 63 noida.
I was told that i would get the delivery within 2-3 weeks but even after 8 weeks now, today on 28-june, i still have no visibility of the delivery.
The dealer is saying that there is some issue at the maruti production end and he is able to delivery the car in other colors than grey.
How is it possible that maruti is producing the car in other colors but not grey.

I have already lost so much time in waiting and still dealer is not able to give any clear picture on delivery either.
This is very unacceptable and non-professional behavior, whether on maruti or the nexa.
Not sure if this is what is called the nexa experience.
