Hi sir, i am g. Sivanarayana my account number is :[protected] cif:99310161
So i would like to close my account in your bank because you have changed my salary account as 10000rupees maintenance savings account so unable to maintain you have demanding amount.
With out any information you have changed my account as normal savings account and deducting non maintenance balance charges so finally i want to close my account in your bank, so i went to your nearest bank and asked them to close it then they said i have to pay non maintenance balance charges, this is very fraud you have opened account for your opportunity, i don't come to your bank to open the account so please closed it.
Thanks
