Wrong bank deposit with CAPITEC BANK

I happened to deposit money to the wrong account with cellphone banking, and I went back to the bank to help me reveas the money but no help at all,instead I was referred to open a case so the bank can get me my money back,now this morning the police also tells me that they can't help me.

My question is if I'm a bank client and they can't help me what is a point of having a bank account in this country. If they can't reverse that money from a wrong account, it simply means banks want us to bank with them time to help us they can't help, so as the SOUTH AFRICAN POLICE SERVICES.

HELLO PETER, ADVICE/HELP
