Cannot correct a Mistake

I used my Standard Bank App on my Android phone to transfer R13700 from my Prestige Account to my Credit Card. The moment the transaction went through, I saw that I mistakenly selected my Homeloan and the money was transferred to my Homeloan and not my Credit Card. Immediately tried to then transfer it form my Homeloan, but it was blocked. Phoned Prestige Banking and spoke to Homeloans. I cannot transfer from my Homeloan as my Access facility is blocked as I have not used it in 6 months. I need to re-apply. Alternatively I need to write a letter of transaction dispute.<br> <br> This is TERRIBLE service! Just help me in correcting a simple mistake I made. Just move the money back to my Prestige account. Undo the transaction without making live totally impossible. Why must everything be so complex with Standard Bank?
