Its my personal experience. I just opened an account on kotak 811 via online by seeing their continous emails, atlast I just wondered by their interest rate etc. but after opening my account I transfered 1700. Rs to 811 after 1 montg of waiting nothing changed, but when I tries to redeem my Money from 811 to my bank they shows you need some minimum balance, they aint told about that on account creation time . And I contacted their customer care , mailed many times no one replied, and after that I got one customer care number I called that number that too not replied. idk what to do redeem my whole balance from this bank. So guys please aware of all terms and conditions before creating account .
