Takealot horrible feedback after account got hacked

So my Takealot account got hacked. No notification of new login nor when they changed the password on my account to log me out. The hacker bought a bunch of MTN vouchers with my refund credit which I received the voucher pins for via email. Immediately changed my password. Sent them a message and their response was it is not their system's fault that my account was hacked but my own fault. I have multiple security protocols in place on all my devices to ensure this does not happen and in 7 years I bought from them this has never ever happened. Now my account is locked from their side after telling me I have to yet again change my password. I am guessing I wont receive my credit back from them. But this is utterly unacceptable. They have lost me as a client.
