HDFC Bank — want my auto payment return fee back

Address:

Muktsar, Punjab, 152026

I paid my hdfc credit card bill amount of rupees 8237 on 5 feb 2019 . But i got a mail in next day afternoon that my autopay was initiated and due to non - availability of sufficient funds a payment return fee will be levied to your card account, if applicable. Then i called the hdfc credit card customer care service to complaint about the same. The customer service associate promised me that the amount will not be deducted from my card. But after that amount of rs. 460 has been debited from my credit card and also rs.0.86 has been deducted from my savings account. Why should i pay the return fee as i already cleared the payment in my card. This is unfair and not acceptable. I want my amount back in my account.
