No Responsibility taken

More than a month ago i got a call (capitec landline number) from a lady saying their is ***** going on in my account, while i was on the phone with her she sent me my banking statements and i needed to go in to my account to see if there was money out of my account, after i logged in without giving any information, she already had access to my account and they did a cash send as well as transferred the rest of the money that was in my account to another bank, I then went to the police and a case was opened and the matter was under investigation, Capitec told me it would take 7 working days to let me know what was going and what the outcome would be, this was not the case, i had to phone every week to follow up and only after more than a month they phone me to tell me that they wont refund my money that was ****** out of my account and i need to let the police take the case on further, and when i asked but how am I in the wrong and that i need to pay back debts that i had loan because all my money was taken out of my account, they said it was because i was logged in on my banking app and that's why they could hack my account,,,,So then what that tells me is that there is no security measures??? and any one can hack my account without them taking any responsibility for the money that gets ******???
