[Resolved]  ICICI Bank — Unethical Auto Debit return fee

I have credit card of ICICI, I always pay my bill manually and never opted for autodebit, but bank started charging me autodebit return fee around 5k with GST and interest charges from following months, when I saw, I started complaint through their complaint section in official website then, I sent many mails to their customers services, I got replies from them that they are unable resolve my problem.
Unethicalliy by hidden charges they are looting their customers.
Finally I decided, I will spread about their unethical business in all social media and internet.
