Sir,
I have already registered a complaint and I couldn't see any action taken on this.
My saving bank account in Canara bank vadakkencherry. My account no.[protected] name -Sreedhi Rajagopal .in my saving bank account balance deduct incessantly due to slab wise nmmb charges. But this charge applies when my balance less than rs.500 as say in Canara branch staffs. But i have maintained my account balance more than 1000.
So pls if wrong charges deducted by system, pls refund my balance in my account as earliest.
