I don't know how they push cash or put cash into ATM machine because I have never seen one but because of the number of counterfeit currency that came when my uncle drew from the same bank ATM and same bank denied it's theirs makes it look like the higher ups of a bank might be involved with this pushing or putting business where they might be adding some counterfeit currency along with normal ones. This is my doubt.
What is Zoho?
Yes, asking them by writing a letter might get some kind of response because I learnt this from my uncle only. Every time any problem occurs he immediately writes to the banking ombudsman or to the bank for clarification. When I was young I used to see him type in his portable typewriter and immediately send letters. He is an orthodox man. Nowadays we are not doing anything like this but post in twitter or facebook by tagging to who ever is responsible.
