Very disappointed

I am very disappointed with blu advance services. I had taken an advance of R50 i paid my advance by purchasing electricity from my capitec app of which both transactions were app**** on the advance debt as i didn’t receive an voucher number. When i tried to take out another R50 advance it says i have an outstanding. What happened to the one i paid? Why is Blu advance now robbing us because this is daylight *******. I have reported this on their platforms but no solution was given.
