Maruti Suzuki India — Delay in receiving the car.

Address:

Mumbai City, Maharashtra, 400008

Dear sir,
i have booked a maruti ertiga zxi model(beige colour) in the month of december with the autovista dealer in bandra.its been 11/2 month but my dealer still has no clue when will the car roll out of its factory.He says that they are not receiving any cars to give..my question is why is the car being sold if there is no production of the same and how long do i have to keep waiting for it.I am expecting a prompt re
ply atleast from maruti on my query.
thanks.
Dr Farah Manasawala.
