Wrong information on the website.

I had purchased Nikon D3400 DSLR Camera from flipkart with the no cost EMI facility for 6 months that was mentioned on the flipkart website as well. After two days of purchase of the product I got a message from HDFC bank (my bank) your total amount is converted into 6 month EMI with 13% interest. I called in both customer care executive and they were giving only unnecessary excuse to me. Why would I pay an extra Rs. 4618 for interest if the NO COST EMI is available on flipkart website. Do not purchase from here, this is only the way the customer will purchase the product and get cheated.
