Payment24 - Defective VodaPay Voucher

I have a VodaPay BP voucher which I bought on the VodaPay App on my phone, on 08/07/2024. I tried to use it an hour later. It declined 3 times. I then asked the manager of the BP petrol station to phone and sort the problem out so that I could get the R400 fuel I had paid for. He was told that he could not help me, that I had to email BP Support which I did on the very same day. BP Support said that it was not their error so they put me onto VodaPay who said that I had a duplicated number which was used on 18/09/2023. VodayPay then put me onto Payment24. I have emailed and requested feedback and I have not received any. It has been 2 days short of a month since this whole saga started. Please reimburse me for the R400 as I have paid for something that I do not have. It is called theft.
