CANT REVERSE PAYMENTS

Hi To the team, i am highly dissapointed with YOU Standard Bank, i made a payment few minutes ago, now i want to reserve, I CANT DO IT ON THE APPPP!!!! I HAD TO DRIVE TO THE BRUNCH AND THEY TELLING ME IT CANNOT BE DONE, I NEED TO PAY JUST TO REVERSE MY PAYMENT. EVEN THOUGH I PAY, ITS NOT GARRANTED THAT MY MONEY WILL BE REVERSED, I AM THAT TATOLLY MADNESS IF YOU THINK ABOUT IT!!!!!! ALL I NEEDED TO REVERSE MY MONEY, I HAVE BANKING WITH YOU FOR OVER 8 YEARS, AM DISSAPOINTED. I JUST LOSS R3300 JUST BECAUSE THE BANK I TRUST CANNOT DO REVERSE PAYMENT!!!!!!
