Issues with buying Prepaid electricity through Standard Bank App

I've purchased a prepaid electricity voucher to the value of R1000 using Standard Bank app on Tuesday 13th Jan 2026. The transaction went off my account but the voucher says its been "used" on the prepaid meter and it hasn't been used because my electricity didn't turn on until I bought another voucher on the same day to the value of R100. You cannot cancel a transaction on your banking app which is very silly and you cannot reissue a token in such an instance. There is definitely a system issue. When I called the Standard Bank call centre I was referred to the Ekurhuleni Municipality. Ekurhuleni says I need to contact my bank. No one is taking accountability to assist me with this matter. The Standard Bank App has changed, you cannot view voucher history nor does the send sms to "32904" work either to see past history of tokens bought. You also cannot see what the status of tokens purchased either on the app either which is also very stupid. I don't know how to resolve. I bought the product from Standard Bank this should be the party responsible to resolve the issue as I'm their customer and I should not be given the run around either. Zero customer service. This is utter waste of time and an unresolved matter.
