No Help for immidate transfers!!!!!

Today in the morning i did immediate payment of R9000 to an agent securing deposit for apartment. we had an agreement and i and paid the money to his account. then later he changed the agreement and wanted more money and i said i do not have it. I called capitec to assist me with reversing the money. an agent by the name on Mpho bluntly told me that she cant help and there is nothing she can do. her attitude is one of the things that upset me as she was just being unnecessary and i had lost of money on top of that. if we can bank with you and when such things happens you tell us you cant help then who should? i really want to give you the benefit of the doubt to revolve this before i escalate it rightfully so.
