HDFC Bank — HDFC Creditcard - Charging Intrest on No Cost EMI

Hi hdfc team,

Pls clarify following. I tried to reach your Customercare but i didn't receive any response .

#1.
I had purchced an item from Flipkart with no cost emi option, i understant that the interest on emi was reduced by Flipkart from the device price. But now in my e statement i could see that i have been charged with MER EMI, INT NBR and i could see 3 components of IGST . Why i am getting charged on No Cost EMI ? Why three components of IGST of 18% each one?

#2

Why my Flipkart EMI amount getting changed (Basically increased) everyMonth ? As for as my knowledge, EMI should be same for each month.veach month?
Please clarify!

Thanks,
FS
