Uco Bank — Amount not credited

Address:

Kolkata, West Bengal, 700040

On 27th April, I was transferring an amount of Rs.25000/- from UCO Debit card to Digibank account, I found that the amount debited from my UCO bank account but not credited in Digibank account due to some technical failure as per Digibank official, but now four days has already passed but the amount still not refund in my UCO bank account, please help.
