Double debited and double billed for 1 purchase

I bought items at take a lot using payflex for R2773 and they deducted the money twice from my account at 18:41. I emailed customer support and they responded around 9pm stating my query has been resolved and my ticket is closed. When I login on my bank my money was not reversed and on their app the bill still reflects twice while on take a lot there is only one invoice for one order. Their phone is not working and they don't even write their working number on the app. I tried logging another ticket but I have not received a response. No consultant has contacted me.
