[Resolved]  HDFC Bank — OFFUS EMI - Wrong Charges taken for the last 6 months on HDFC Credit card

I have been charged continuously since i agreed to increase my credit limit on the HDFC credit card which was ofcourse free of cost but my dues are never ending despite paying everything off I still keep getting charged for OFFUS EMI which no one from the customer service desk could ever confirm. I am also being charged GST for God knows what reason. I have been paying since the last 6 months and now have not paid for this month and HDFC Bank has been calling and harrassing me with calls by customer service executive shouting at me to pay my dues and calling scolding me for not being regular whereas i have been regular. I need my money back for this EMI charges that are fraudulent. I opened an HDFC account because I thought this was the best and most honest bank but I think it's time to I realised how this bank has been duping me for money. Is this how HDFC has been making money????
