Poor service

Poor service .I was at work while i received a message from my account saying i had a transaction purchase of R597.06 which i did not make .i stopped my card and contacted their customer service .They told me its an online shopping .Ever since i opened an account with capited i never did online shopping .hours later i went to their branch at Hyper Rama they told they are going to do investigations and contact me after 2 to 3 working days. Even today i never received any call from Capitec.The sad part is when they told me im going to be charged when they are going to dispute my money .they said if its outside South Africa they will charge R150 then around SA R60 .I was asked them how can they charge me while its their negligence on mine .I thought my money i save with capitec but i was lying to my self .helloPeter please help to get my money back.
