HDFC Bank — Amount not credited back still in my account after voiding wrong swipe

Address: Kalamsery Municipality, Kalamsery, Kochi

At Kalamsery Municipality, they have swiped mistakenly 126300 instead of 1263 at HDFC swiping machine . Amount was voided immediately but still not reflecting after 3 days too.
It's too bad that we have to suffer for some one else's mistake.
