Hyundai Motor India — cng fitment

Address:	Mumbai City, Maharashtra, 400054
Website:	www.modihyundai.com

I have purchased grand i10 car from modi hyundai showroom at santacruz east. The delivery of car was taken on 10th december 2017 from the showroom. At the time of booking, for the said vehicle i have opted for cng fitment from modi hyundai and paid rs. 70, 000 (Debit note no. Dn-ssr-001017 dated 21.11.2017) for the same.
This is my first vehicle and i was unaware about the necessary accessories to be checked at the time of taking delivery of vehicle.
Later it was found that cng plate was not given with the cng fitment. I came to know it while filling cng at pump house when a person asked me about the cng plate and refuse to fill cng without authorized plate. It was in the second or third week of december 2017.
I have contacted the sales person, ms. Rumina shekh, to co-ordinate with this matter and provide me the plate. From the second week of december, i have made several phone calls to ms. Rumina to follow up the matter. Every time she asked for an extension period to sort out the matter giving the various reasons “like you will get the cng plate from workshop”, “you personally need to go there”, “we have contacted rto office and they will give the plate within two days”, “give me two four days to sort the matter” etc.
I have personally visited the showroom and conversed with her and other sales person, mr. Akib. They failed to give me proper solution. Now, i am fed up with the poor service provided by modi hyundai showroom staff.
I am driving my car on petrol from last two months even after having installed proper cng kit from modi hyundai on a huge payment of rs. 70, 000/-. I drove daily 80 km on petrol bearing the additional financial burden.
After two months the sales persons has come up with the new reason for the matter saying that the account section have not made payment to the cng provider.
Is this my mistake of buying the car from modi hyundai showroom? Why should i bear the burden? What the hell account section is doing with the payment of rs. 70, 000/- i have made towards cng kit? When am i getting the cng plate?
