Central Bank Of India — money deducted from my a/c without any generation of cash at atm

I made a transaction at central bank of india lanka varanasi of 2500.. But atm said its out of cash so i cancelled my transaction and move out from atm. But then i got the msg that amount has been deducted. So we lodge a complaint in cbi branch of lanka. They made us to wait one whole week and then closed our complain by saying the transaction was successful but we didnt received the cash.. Please help. A/c no [protected]
