Reversal of immediate payment from Capitec Bank

im very dissapointed with the capitec bank call centre, they are rather useless and time waisting . all they are able to tell you is that It CANT be done. on the 11,12& 13th of september i was misled into believing i was buying products such as shoes, hair and whole lot more for selling and i was promised assistance in selling my products. In august everything went well and i got my payment from the company after they assisted with most of the sales. I then made another order in September and i paid an amount totalling R56400 for the stock but i have not received any of it and cannot get hold of the owner or the person in charge. i then requested Capitec bank to reverse my immediate payment but i was told it cannot be done. kindly advice me how to persuade this bank to reverse my money back into my account
