State Bank Of India [SBI] — Money never came out of the ATM machine

Address: 411028

I tried to withdraw sum of Rs.10, 000 from an ATM center on 7th February, 2017.
The sum was deducted from my bank accounnt (received debit SMS)
But the money never came out of the ATM machine.

I had been to my home branch (Hadapsar, Pune) for asking refund.
They did not register complaint the next day (8th February), despite of me giving a written application.
After waiting for few days for auto-refund, I again visited (27th February) and this time they registered complaint.

But the money is not refunded to my account yet (28th April).
