Indian Bank — I'm complaining about refund amount

On 13/4/19 i had swiped my atm card and i try to withdraw my amount 200 but machine doesn't respond and it showed like time out. 2 times i try to do this but 2 time also it showed like time out. But my money 200 alone was deducted 2 times by indian bank. 200 they credited my money back but remaining 200 was not credited back. Till now i didn't receive my money back.
