Transaction dispute

In July 2020 I made a transaction to pay Annique health about R2200, because then I was experiencing frequent ********** transactions Nedbank revered the transaction, however my order was released and delivered to me by Annique. I then paid annique from my Capitec account. In August 2020 Nedbank called me after making their investigations and told me that the transaction made in July was legit, I agreed and indicated that I had already paid the merchant from my other bank account. However the consultant I spoke to indicated that they will still deduct the amount again and I will have to speak to the merchant (annique) for refund of my money. Although I didn't understand why do they need to deduct my account whilst already paid the merchant the transaction went off on August 28th 2020. I then engaged Annique and provided them with statements from Capitec and nedbank and annique indicated that only amount received was from Capitec not Nedbank. Since September 2020 I have been struggling to get my R2200 from nedbank and I find it frustrating as that money I use it to try to earn an income yet am faced with this predicament that I don't know how to solve as nedbank show no interest to assist although I have contacted them numerous times
