Maruti Suzuki India — not received a car after getting the commitment

Address:

STATUS tower ,B-701,opp T V tower,near Sal hospital., Ahmedabad, Gujarat, 380054

Hello,
I had booked a car ertiga vxi grey colour on january 21 2019.
I have a written confirmation of giving the car in 8-10 weeks and a verbal confirmation of giving the car in six weeks by vijay bharwad and jay shukla of kataria automobile makarba branch.. But 12 weeks have passed but i have not yet recieved the car & nor any of the commitment when will i get it or any reason for delay... I am very much upset and surprised that how can maruti do this..
And it was said please divert to any other colour or any other model in ertiga... As company is not giving us grey ertiga vxi
. Because of some of these distributors maruti is spoiling their image... This is the last time i will purchase any maruti car... Now i have diverted to hyundai...& i had to purchase a santro sportz on 29 march 2019 (Wanted to gift my parents).. Just because of delay... I was not having the car.. I had a swift dzire vxi which i had purchased from kataria in 2012.. And i had committed to a person to give him in march 25 2019.. As i had received the same commitment from kataria... But i can't break my commitment...
I want to know what has happened??
Is my car ertiga grey is sold to any other person to earn some more profits??
I request you to please give me an urgent reply and if needed, transfer my booking amount to any other distributor....
I will ask a suggestion by you that what should i do?
Should i go to consumer court or should i wait for your reply...
Please it is a request to answer soon...
Regards
