Edgars Thievery and non response

On 15 November 2020 I bought perfume at the Edgars East Rand Mall. At the store, the sales person advised that the transaction did not go through on my account and that we should go to another machine. After getting home, I saw on my phone 2 messages showing that both transactions was processed. I emailed Edgars immediately to notify them of this. I've forwarded this email almost on a daily basis without any response. Seems like they refuse to reverse the transaction and that the sales person maybe did the double transaction on purpose to get himself something from the store. I will be closing my Edgars account asap and spread this story of theft as far and wide as possible.
