I have made few emi transactions with my idfc first bank credit card. Later I cancelled those as I wanted to make full payment. I was charged emi processing fee and GST (1% of amount+GST). While cancelling emi transactions, I was charged force closure fee and GST (3% of amount+GST). Usually icici and hdfc will refund emi processing fee and foreclosure charges are not levied if emi is cancelled within 5-10 days. These charges are exorbitant in IDFC credit card. Are there any RBI guidelines regarding same ?
