Hi
My name is Lowkya. I'm from Andhrapradesh. I went to draw 10000 from SBI ATM on 4th Sep 2016. There are two ATM machines in the center. I tried drawing money from the machine. I've given my pin and entered the amount 10k. I have NOT received the cash but got a receipt of some error. And then, I immediately moved to the very next machine and I drew 10k without any hassle.
While doing this transaction I didn't even heard the counting sound (we can hear a counting sound right Grrrahhhh Grahhhh before dispensing money) from the machine1.

And I counted the money in the center itself and left the ATM and traveled to my native place.

Then I got text message two times after 50 min of my withdrawal showing two 10k transactions and debited 20 k from my account. I didn't think much about it as I heard a lot about these kind of messages from SBI due to some technical problems on their end.
Later I went home and checked my balance with my personal banking account and got shocked that It showing two 10k transactions. Informed my friends and they suggested me to raise a complaint online and given the toll free number[protected]. I did the same and waited for 7 days for the resolution.

After 7 days I got a message that the transaction was successful and we sent relevant documents to the home branch. I went to my home branch and surprised with their ans that it can not be refunded as it was a successful transaction.

Now I lost 10k and in dilemma what to do next whom to complaint. Forgot to mention there was no guard at all.

Please let me know how to proceed further.

Thanks in advance for your help in this.
