Hi i m from karaikal, my father had a loan in indian bank neravy branch, my father passed away two yrs back, so i settled the loan amount as per ARC instruction on 30.9.2020, they sent me NDC and also to bank, but still they did not provide my documents, i ran to the bank day by day last 3months, and they simply said document is missing. They didnot told me the file was missed before i paid the settlement. After i paid it they told me like this. Is this the way you treat your customers and their valuable things.I dont want to say further, i going to raise a complaint and file a FIR againts indian bank and i dont know how many customer documents they are missed.
