Double debit and call center says its the banks problem

I tried to do an order for some groceries this morning using the sixty60 app, during the checkout stage the app gave a timeout in the payment section and said the payment had timed out and failed, and at that moment an SMS from Capitec comes through informing me that the 435 rand had been taken off my account, back to the app and i try to refresh the payment option and again the app gets a timeout error and again another SMS from Capitec to say that another 435 rand had been taken off my account !!!

So I contact the call center and a Cleo Menzi informs me that the app has timed out and that Capitec must reverse the payments for me to get my money back and that there is nothing Checkers can do ...

Such incredibly bad service .. Checkers will never see another cent from me again !!!!
