Standard bank

I did a transaction on the 5th October which I believed did not go through on my debit card as I received an error message saying " payment could not be processed due to a technical error". Tried the payment on my credit card it went through.

Only for an sms notifyinf me that my account ( debit card) was debited.

Notified the bank on the same day, was told to call the merchant and notify them and also advised to wait 2 days.

I did that, on the 8th called again, referred to Recalls, filled the form and sent it back. Only to receive notification that they can do it I must call disputes.

Called disputes, been on the phone for an hour and I'm told to call the merchant to refund me.

Standard Bank who gave me an error message when I made the transaction cannot do anything.

The back and forth is draining, had I nor received an error message a duplicate was not going to be made at all.
