Poor Customer Service - Double Charge Reversal Request

On the 19 of August 2021 I purchased 2 items from your Ladysmith Store and paid with my bank debit card. The cashier was under the impression that the transaction had not gone through and subsequently took another payment of my account. I later that day returned to the store with proof that the transaction had gone through twice. The manager assisted in requesting that I provide proof by means of e-mailing my bank statement to him. He later that day copied me in a mail where he requested that the second payment be refunded to me. It now 7 days later. No communication and no refund. Can someone please inform me when this refund will be effected.
