State Bank Of India [SBI] — Challan wrongly deposited by bank

Address:

New Delhi, Delhi, 110065

Sir, we are facing harships because of sbi bank employee negligence. We have deposited challan in sbi friends colony branch but employee deposited that challan in other. We have got income tax notice because of not showing challan in 26as penalized with 12520 .. After receiving such notice from income tax we have contacted from sbi friends colony branch to correct their mistakes.. But they refused admit their mistake from 1st instance then later taken all the details of challan and assured us to provide a letter from bank for wrongly submitted the challan.. After that we used to visit bank to get that letter from bank but bank employess making exuses again & again.. We are harassed by bank again & again..
