State Bank Of India [SBI] — cash not dispensed by atm but money deducted.

Dear all,
On 11/02/19, i went to sbi atm located at nagatilla, silchar to withdraw rs. 8000/- from pnb account. While i was withdrawing money, my money was deducted but i didn't receive the cash. Now i got the information that sbi authority is not giving the cctv footage of the particular time to the pnb authority for which i am unable to get my money back.
