Canara Bank — amount deducted from bank account but didn't receive cash at atm

Hello,
I was trying to withdraw money from a canara bank account on friday 9th august 2019. I was trying to withdraw 500rs from the atm, i entered the amount i received a message saying 500rs were deducted from my bank account. But the atm showed an error of transaction timed out and didn't receive any cash, i contacted the bank they said it will be refunded automatically but i haven't got the money yet.
Please help me through this.
