Double Deduction - Poor Service

I am writing to report an issue with a recent data purchase transaction made through the Vodapay app. On 17 Oct, I made a data bundle purchase through the Vodapay application. While the transaction itself went smoothly, I encountered a discrepancy that has resulted in the double deduction of funds from my bank account. It's now stories all the way and the matter will take longer than when they deducted the money.

I received two separate SMS notifications from my bank, indicating that the same amount was deducted twice for the Vodapay data purchase. However, both the Vodapay app and my bank app show only one deduction, leading to confusion and concern regarding the double deduction.

I have reached out to both Vodapay and my bank, but unfortunately, they were unable to provide a clear resolution to this issue, Vodacom Consultant promised to send look into the matter and send a reference number, which i have not yet received. Nedbank is unable to trace, but the money in my account went out twice for a single transaction. How does that happen?
