Double Debit

I am extremely disappointed in the level of service from Standard Bank. On 10 March 2021, I purchased fuel and oil at BP Edenburg. This transaction went off for the amount of R445.90. On 12 March 2021 I was in a store trying to swipe and told there are insufficient funds. After checking my banking app I realised the transaction in 2 separate amounts went off again for BP Edenburg. 1 for R400 and 1 for R45.90 amounting to the R445.90 I swiped for on 10 March 2021. I have called numerous times and on Saturday it was escallated with Ref Number ***. Today 15 March 2021, I was advised there is a deadline of 17 March 2021! This is absolutely ridiculous that a client must wait 3 days for an error that occurred from Standard Banks side. I expect this to be resolved urgently.
