HDFC Bank — amount deducted but not credited to receiver

I have made imps transaction from my hdfc account to my canara bank account, amount got deducted but not received in other end. Its not refunded either below is the details

Account number : hdfc : [protected]
Account number : canara :[protected]
Date of transaction : 29/08/19
Check/ref no : [protected]
Amount deducted : 8000

Please check on priority see problem is i never came to know about this untill yesterday when got message from hdfc my loan emi is not paid which is linked to canara bank... My perception was as i did not receive any error i never bothered to check balance but now as i missed emi it will reflect bad on my credit score also all due to pathetic hdfc service... Which looted my money
