Saraswat Bank — complaint against withdrawal amount deducted but not received.

Address:

Mumbai City, Maharashtra, 400069

I have saving account in your andheri branch. My account number is [protected].
I had withdrawn amount of rs 2000 from indian bank atm (Madhav nagr, andheri wgreatermumbaimhin - s1aa0231-txn ref no[protected]
Dated on 14th september 2018 timing 2:26 pm.

Now an issue is that my transaction amount 2000 was deducted from my account but only 500 withdrawn but remaining 1500 not came out from atm.
After that i visited the same bank branch (Indian bank) but they suggested me to visit the home branch.
Next day on 15th september i visited to my home branch (Andheri east) they ask me to fill a charge back form. I filled it up but i got a message that my charge back application is rejected.
So i request you to suggest me how i can regain my remaining amount of rs 1500 as soon.
