ICICI Bank — Surname spelling correction

Address:

507001

I'm holding account with the icici bank from 2006: a/c:[protected]. There's a spell mistake done in my surname (Correct spelling : japati, wrongly spelt as japathi) by the bank authoring while opening the account. Since then i have been contacting the branch in khammam, telangana to correct it - with one or the other reason they didn't do it. I went to the branch with my passport, pan, driving license, aadhaar card, and ssc certificate copy to correct the surname spelling. They are not ready to accept those; instead demanded a declaration in the newspaper for the correction which sounds meaningless. I said it's not a name change, it's a correction of spell mistake done by the bank people. I've even asked to show/tell me the proofs considered while the name was typed - they don't have an answer.
I don't understand for the mistake of bank people why should i suffer from linking the bank account to my income tax account.
Just for the reason that i don't want to loose the banking history of 11 years, i'm sending the requests, but now i would like to close the account.
Thanks,
Kautilya kumar japati
