ICICI Bank — Auto debit return fee

Hi,
Issue: auto debit return fee.

Summary: i have not opted in for auto debit service i want my money back for all the months i have paid for the service.

Off late there has been extremely disappointing customer service for me. I have been charged for auto debit fee for quite some time now, i dont know for how long, as i never activated or authorised to enable that service. I reached out to various credit card card related custimer service but the resolution has not been provided, i confirmed from the credit card executive who provided me the credit card and he says he has not activated that service. I have just being redirected to branch, customer service, credit card manager and now here. My expectation is i want the money to be rightfully reversed to my account that i have paid for that service so long.
