beneficiary on app is Totally wrong!!!!

I wanted to pay a capitec Registered beneficiary, after I selected the one I choose, it asked me to enter a account number, so i typed in the Place where the Money must goes to account number, when the notification was sent to me, I saw that their account number was the Reference (IT NEVER ASKED ME FOR A REFERENCE NUMBER) I am not willing to pay R150 for a reversal and wait up to 14 days +, if your system was showing that it was by Reference Number (as all beneficiary shows) I would understand the mistake is from my side, but its not!!! No one at the bank are willing to understand or try help me. The people I paid said I must fix it from your side!!
