Axis Bank — excess payment charged by bank

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201303

Sir
I purchased an ac from flipkart, using axis bank credit card on no cost emi.
Total amount of 30780/- was spent using credit card.

Order id - od[protected].

I opted for 6 months no cost emi option.

At that time site of flipkart was showing rs 5278 for 6 months
.
Now i have received an email of axis bank that my installment amount for 6 months is rs 5311.04.

5278 * 6 = 31668/-
5311.04 * 6 = 31866.24/-

Kindly tell me why i have to pay more than the amount spent on my axis credit card when i have purchased the product on no cost emi.
