Theft of funds

On the 3/12/2021 I went to Capitec to request the refund of unauthorised debit order of a funeral cober. The guy by the name of Kumbi helped but he was so arraogant towards me and he told me since the funeral is active on their system they won't help me refund it. He says I have a bad attitude and I just leave the branch. When I speak to the call centre they also refused to refund me whereby I cancelled their funeral policy long tine. Remember I'm not working and I borrowed money from someone so I can sort things out and now Capitec refuse to refund me. Why should I suffer the consequences of the consultant who failed to do her Job now it should bite me. Capitec cannot expect to reach the target by forcing me to keep their funeral cover whereby I'm not working and I cancelled it by September. Now I'm being told to go to where I cancelled it. I feel like now this is theft from Capitec on my Account. I'm unemployed yes and can't afford the funeral cover so why do they still force me to keep the funeral cover. All I want is my R588,25. I borrowed R1000 now they take R588 just after I put R300 petrol in my car. This really unfair. The manager didn't even want to be part of this whole thing. But the assistance manager Kumbi told me to get out of the branch if I don't need help cause he can't tolerate my selfish stinky attitude. I want my money please
