ICICI Bank — Unfair Trade Practices

I have purchased a mobile from Flipkart under 'No Cost EMI Program Discount' for a tenure of 6 months as the longer tenures were having interest charges. But after having completed the transaction using ICICI Credit Card, I found out that the ICICI Bank is now imposing charges in the name of Processing fees and various Interest Charges.
I have previously done multiple similar transactions with HDFC Bank but never faced such an issue. If ICICI Bank cannot afford No Cost EMI transactions, then it should inform before hand instead o[censored]sing such dirty tricks to extort money from its Customers. ICICI Bank should be penalized for using such Unfair Trade Practices.
If I had known before, I would have used my HDFC Card for the Transaction.
