Indian Bank — rude behaviour, lack of customer service, giving out fraudulent money from atms

Address:

6th Block road, Koramangala, 560034

I had come to the indian bank atm located in koramangala, 6th block, bangalore to withdraw ₹3000 cash and the atm gave out one note which was coloured with blue ink. So i went inside the bank to ask about this and they are refusing this request to exchange the money. First they asked to come another day and so we did. Then they started to tell us that their atm does not give that kinda money. Even when we tell them to check the cc tv footage they don't check it and don't look at the proof i had of the transaction. This is a very serious concern for me cause i'm a student so please look into it as soon as possible.
