Hi hdfc team,

I had purchced an item from amazon on emi which was supposed to be no cost emi, i understant that the interest on emi was reduced by amazon from the device price. But now in my e statement i could see that i have been charged with two components namely mer emi int nbr and finance charges. According to me it should have been only a single charge rather than two things.
Please clarify!
