Punjab National Bank [PNB] — atm debited money twice

Address:

144001

From last one month i am hunting to get my money back. I debited 10000 rs through atm on 20 june 2018 at about 8:18 pm and got the money but. Again at around 8;24 pm same day i got another msg of deduction of 10000.
I only got 10000 rs but 20000 rs has been deducted from my account moreover funniest part is i was not thr in the atm when i got the second msg at around 8;24 pm.
Thrice i filed the complaint but of no use this is literally a harasment and i must say pnb is the worst bank in terms of service they are least botherd that one of their customer since 18 years is facing problem instead of solving my problem they people are not even bothered.
