RBI on if accounts get debited but you do not receive cash :-
As per the information provided by the Reserve Bank of India (RBI) if your account gets debited but you do not get the amount from the ATM then the banks are supposed to reverse such transactions on their own.
Lodge a complaint :-
It is always a good practice to lodge a complaint with the card issuing bank or ATM owner bank at the earliest if your account gets debited and you do not receive the amount. Banks/WLA opperators display the name(s) and the contact number(s) of concerned officer(s) / toll free number(s) / help desk number(s) in the ATM premises itself. Therefore in order to lodge a complain you will have to look for the number in the ATM premises.
