C Number Voucher

I am soo annoyed with Capitec Bank, i tried to redeem a voucher and the voucher said it was successful however I did not receive the money, the Atm did not have money and there was no prompt stating that there is no money in the Atm this is R2500 we are talking about, the voucher says redeemed but no money came out, this is my child's school fees money! I am soo upset right now
