***** out if cash

My TymeBank ZA account was hack through ********** on the 1st of June. They withdraw R1100 how they got my details I don't know. Im in Cape town and it took place in Pretoria where the money was withdrawn. After numerous calls and sending emails with no assistance. They get back to me 10 days later. Only for the investigator to tell me today I wil not be getting a refund cause my credentials were used. Im so frustrated and angry at this moment my last cash that gets me through the month. I've tried calling again to speak with a manager or team leader only to hear they are in meetings. They have told me to go to the ombudsman what's that going to help me. Even there own employees say that there security system is not that good. If only I knew that before the time. Im disgusted in there service telephonically and emailing system. Where does this leaves me getting my hard earned cash back. I see im not the only one that went through this who can help us
