Maruti Suzuki India — delay in getting booked maruti breeza

Address:

Pathankot, Punjab

I have booked a maruti breeza model zdi plus (Grey colour) on 25 june 2018 at pathankot vehicledes pvt ltd with booking amount of rs 11000/- against booking number sob18000850 with csd facility being ex serviceman and was assured that i will get delivery of vehicle before 2/8/2018 as my sons marriage is on that day. Now your dealer is making excuses and telling to take red colour car which i don't want stating grey colour will be delayed by 15-20 days, this delay is not acceptable, i am ready to take white colour before 2/8/2018
Please look into this matter and get me car delivered on time non delivery of car will dampen our marriage happiness
Waiting for your positive reply at the earliest
