Pathetic service no customer centricity

I have recently lost money which was meant to be safer in my bank , how? I was not aware that my phone number was not active apparently there was porting to Telkom actioned hence I lost the connection. I found out when I called my service provider. After I called my bank they advised that I have nothing left all my funds were utilized by an unknown. I was provided with a ref number so I could wait for the feedback. They advised there's nothing they can do that means I lost my money it is now my problem. I told them I am not happy with the feedback because I wasn't even aware that this bank doesn't have that security feature of not transacting immediately after changing any details meaning if they had that security then the ********* wouldn't have transacted successfully. I was referred to their complaints centre. I sent an email got another ref number and they advised 24 hour TAT it's been a week now. I sent another email yersteday they ignored me still... I don't know maybe it's a matter if who you are fir them to care. But capitec DOES NOT CARE they can't even pretend.
