Bank Of Maharashtra — behavior if the staff

Address: Bank of maharashtra SAVEDI branch, Ahmednagar, Maharashtra, 414003

Bank of maharashtra
Savedi branch
Ahmednagar

I went to bank for withdrawal of cheque
Wrong date was written on the cheque
So o signed on check and written the original cheque but the cashier was very rude and told me to bring a new cheque in a rude manner
I accept it was my mistake but cashier's are government servant they should behave in polite manner
The cashier was 50 year old lady and was very slow the young staff in the bank are very cooperative and polite but the old staff behaves like customer are their slave.
Please someone look into the matter.
