Ewallet

I did an ewallet to my brother however when he went to the ATM to withdraw the money it says the phone number is wrong we verified everything that I have in the correct number and he’s also doing the same when withdrawing the money from the ATM it’s still giving the error. He’s able to create the pin and view the balance from the same number but unable to withdraw it. I went to an FNB branch and was told I will be charged R55 for reversal, how do I get charged for something that Is not my fault I punched in the correct phone number but FNB wants me to pay R55 to reverse my money due to their system glitch.
