Money transferred into builders card not reflecting after system error

I have a builders purchase card used for work-related expenses only. On 20 November 2023, I logged onto the builder's website to transfer R3563.85 from my bank account onto the card. After completing the transfer details on the secure payment system, I was then directed to builders to complete the transaction I was not able to due to a "system error". On 22 November the amount was deducted from my account but this did not reflect on the builders' card. So I deposited another R10.00 to test whether perhaps I had made a mistake the first time, I then got the same "system error", two days later once again R10.00 was deducted from my account. Again the R10.00 didn't reflect on the Builders' Card. The builders' staff in Newton Park, Gqeberha although they tried to assist, could not shed light on what might have gone wrong. Builders please investigate because my money was deducted twice and the money is not in my account nor the builder's card.
