State Bank Of India Atm At Omaxe Mall In Gurgaon — cash dispensed 1000 less as opposed to amount entered on the system

Address:

Gurgaon, Haryana

I entered an amount of Rs 7000 to be withdrawn, however the machine only dispensed out six thousand in denominations of Rs. 500 x 12 just inorder to check that probably the error were corrected immediately withdrew another Rs 1000/- but the loss was mine as the total amount of withdrwal reflected 8000/- while I had only 7000/- in hand

Please advise this way in which my mony can be recovered - Thanks
