Edgars Refund Policy is Absurd

I purchased a shoe from the Edgars store at the Centurion mall on 10 October 2019, I took the shoe back on Friday 18 October for a refund as the shoe was not a comfortable shoe, the shoe still had the tags on, the lady asked for my Credit card as the shoe was purchased with my Credit Card, she supposedly actioned the refund on the 18th into my credit card and notified me that the refund would take 48 hours to clear into my bank account, I am still awaiting the payment, I contacted my bank which is FNB and my banker advised me that Edgars needs to authorise the refund with their bank, this is totally unacceptable as I was told that my money would be released within 48 hours, we are passed the 48 hours and the refund still reflects as pending on my credit card statement.....I don't think I would buy anything else from Edgars as the customer service is absolutely absurd, my reference number as per my Refund receipt is ED***, Authorisation Number is 834277, the amount owed to me is R349.95
