What power does the bank has to hide the transaction in the bank book statement which means how could I know where did my money gone
The bank had taken my money with out any information and at least it should state in the bank statement but it is not showing is it acceptable under consumers act ?
It is perhaps 4 th time my money has been taken by the bank no proper information and even hiding in the statement about their activity of taking my money
1300 + what about Lakhs o[censored]ninformed customers they can not know that their money had taken by the bank for ever since it they don't represent in the bank book statement
