Rs. 500 less from ATM withdrawl

On 8^th Nov, 2015, I went to ATM of HDFC bank located in the society where I live. I used SBI Bank card to withdraw Rs.10000/-  and to my utmost surprise only Rs. 9500/- came out. In place of one thousand note there was one five hundred rupee note. Five hundred rupee was inserted between the thousand rupee notes. I noted the number of that ATM branch and called the mobile number mentioned on a slip attached to the ATM as there was no security guard. The person on phone suggested me to file a complaint in the bank whose card I used to withdraw money. I complained to the customer care of SBI bank as I used SBI card to withdraw money regarding the refund of Rs. 500/-. But my complaint was rejected saying that the 'ATM transaction was successful'. I felt cheated.

I request you to be careful while withdrawing money from ATMs. If any of you have faced the same problem and wish to file a case in consumer court then you can contact me.
