Duplicate transaction @ Cash Build

On 01/03/2022 I went to Cash Build in ThornTree Soshanguve to purchase paint of the value of R2259.85 using my Woolwoths credit card, the transaction was duplicated and i was told that the funds will be reversed. i gave the transaction a couple of days to ensure that cash build bank their receipts for those transactions to appear on my bank statement and also to confirm that i get refunded automatically. As soon as i realised that the transaction still appears as duplicate on my statement, i took my statement to Cash Build Thorntree for refund. I was informed by the lady called Tsholofelo that she will give me a call yesterday (07/03/2022) which she did not, i took it upon myself to go in the store today (08/03/2022) where i waited 2hours and 30 minutes only to be told that their accountant told them that they have refunded all their clients without any proof. i need that money urgently to push my business. Not even their manager bothered to come to the front to explain and show remorse of the situation.
