Charges on Credit Card Payment Reversal

On the 23rd of September I made a purchase on the Edgars' website using my credit card, I then got a message that I entered the incorrect card details, however an amount of R589.85 debited from my account. I then contacted Edgars to request a reversal but was advised to log a dispute with my bank instead. I logged a dispute and the amount was reversed but I was charged a fee of R195, which I really believe that it very unfair on me. That is a lot of money and could have used it to but my child some shoes. I am very disappointed with this and would like Edgars to do something about it
