Hyundai Motor India — Car prices increased, showroom deducting Rs. 3000

Dear Sir/Madam,
I had booked one creta base model diesel on 22nd January 2021 at Dream hyundai Sector-3, Noida but price for same has been revised and now new car would cost me one lac Rupees more so in this case I do not wish purchase this car as this increase means I would need to pay almost 10% more for same product. I had quaried with sales executive that cancellation charges should be waived off as company has increased prices and it is unethical to cut charges in such a case but he said it would not be waived off although it is true that it is written in form that cancellation charges Rs 3000 would be cut but is it not bad trade practice to increase price and than ask for cancellation charge as customer has not withdrawn his part of agreement but showroom has increased prices of product. If prices can be increased like this what is the logic of such advance booking isn't it illegal trade practice to first offer something and than increase price but if customer withdraws charge him with cancellation. Isn't this agreement illegal in which one party is increasing prices at his will and other party cannot even withdraw you are cheating customers by practicing such illegal trade.
I do not wish to escalate this matter further either cancel my booking and refund my full money or offer me car at price I had booked, I am not the one withdrwing but it is showroom which is from its commitment hope to get resolution to my problem at earliest.

Thanks and Regards
