Maruti Suzuki India — Complaint against new car booking miscommunication

Address:	411019
Website:	www.wondercars.net

I have booked a Vitara Brezza LDi option on date[protected], the car was booked by sales executive 1. And the delivery date was given as 2nd July.

After 10-15 days I changed the variant from LDi to Vdi option. This time the sales executive-1 was on leave, so I was greeted by sales executive -2. He noted down the changes I want and took signature on the papers where he written updated variant details. And informed me that the new waiting period will get applied (somewhere August will be the new delivery date)
I asked him about the new receipt but he told it is not required and assured me that he will submit those papers to sales executive1.

After this I tried calling sales executive 1 for couple of times to enquire about the status, but most of the time she was on leave.

Today morning I got call from sales executive1 to inform that my car (LDi option) will be delivered in this month

Shocked to here same from her, I said I changed the variant to Vdi option, and started arguing with me for not informing her about the change.

And now my new delivery date is in November. 2016..lol

My question:
Do you really think this is my mistake that I trust on Maruti and booked a car.
I really needed to have a car before rain starts. I sold my Mahindra Scorpio to arrange finance.

I and my whole family was mentally prepared for welcoming car before rainy season.

Kindly help me and my family to get out of this situation.
