Chowgule Industries [CIPL] — delay in car delivery

This is in reference with the purchase of a Maruti Suzuki Swift Dzire TourS on 28th Dec 2018 from Chowgule Industries Pvt Ltd Ambegaon Pune.. The purchase was for purely commercial purpose hence I had a talk and proper discussion with your sales executive before paying the full amount. After all the necessary procedures i was given a confirmation that I would be receiving the car by 10th Jan 2019, which I also took in writing. When the date came, even after calling multiple times no response was received, and after 2-3 days I got to know that the sales executive with whom I had a talk with resigned and someone new took his place.
Even though the date was fixed he gave us some talk about Govt rules and a new date of 20th has been reassigned. As it was the delay from RTO side i was ready to wait for some more time. Not to mention I have to pay the EMI and Driver's Salary even without doing any business. Since it was because of Government's proceedings, I decided to wait for another 10 days and thought that I can use that vehicle for at least 10 days in Jan to recover some of the losses.
But to my surprise even 20th Jan passed and I keep on receiving new dates 22nd then 25th, then 31st and now 6th Feb which is highly unprofessional. As you are also into business and must know the importance of dates, if I would have been told from the start that it would take so around 1-2 months at least I would not have gone around and finalized a Driver to whom I am paying unnecessarily even though I didn't receive the Car.
I have called your sales manager so many times but everytime they just give a talk about some other government rules.I'm bearing unnecessary losses because of your mistakes and i suppose you as Chowgule Industries is sole responsibe and answerable to the customer. If I would have known it 's gonna turn like this from your side I never would have purchased it from there because i was well known to the fact that i have to give some fixed date to my vendors to whom i'm attaching my car. While making the payment, I was told that the money is non-refundable I trusted & agreed and I expected the same from your side as well that since you have given in writing I would receive the Car on given date or 5-10 days of buffer some one can manage either. But it is being about a month delay in delivery.
I am highly disappointed by the service and lack of professionalism, even though it may be because of Govt rules its understood that you are in this business for long should be aware of these things. I hope you would take all these things into consideration and would take proper action asap needless to say I am also looking forward to how you are going to take action for the loss I have suffered because of your fault. It is now up to you to salvage our belied expectations.
