Vodapay withdrawal at Picknpay Mokopane

On the 23rd of June 2025 I went to picknpay at Mokopane to make a Vodapay withdrawal of R900. When I got there the cashier told me that there was a network issue on her till and that I must try other tills, I went to the other one and I was told that my withdrawal voucher number was invalid. The next day I called Vodapay to check what was wrong with my voucher and I was told that the voucher was redeemed at 17:37 at picknpay Mokopane mall(which is the exact time when I was helped by the first cashier). I went back to picknpay and showed them the proof that indeed the money was withdrawn and on my arrival I spoke to the till manager who told me that he was going to initiate an investigation. And since then I haven't gotten any feedback from them. This is very inconveniencing to me because that day I had an emergency whereby I needed to use that money. I even had to go borrow the money from other people. Please assist me to get my money back
