Address:

Dear sir,
Myself byasadeva mohapatra having saving account no - [protected] in standard chartered bank, chennai. I want change my address in bank record of standard chartered.
For that i went to bank along with another banks statement & given request for changing of my address. But the bank officer of standard chartered, adyar branch clearly said that they ll not accept the statement of another bank. He is asking to give statement with bank seal & signature. But when i asked to that officer where it's written that u need this type of statement, he was silent.
Pls do the helpful asap. Otherwise i am going to close my account in standard chartered bank.
