Capitec bank

There was an online purchase for R723.53 by someone named BILLPHO.COM on my savings Account, I was at work and had my card with me, never ever purchased anything online using this card, I immediately phoned capitec the lady wasn't very nice and told me they needed to block my card and I must get a new one at a cost of R60 and the matter would be investigated I asked how long this would take she said she didn't know. The incident took place on the 27th May 19 on the 31st of may I called to check on the progress I was told they are waiting for the company who billed me to release the funds back into my Account but our call cut off before we could finish so I emailed customer services, the response on email was that they are waiting for me to get a new card which I had replaced 3days earlier because I needed to get some money. Their stories don't match ?! I then tried to get hold of this company and the information on Google is very limited they have an overseas telephone number which doesn't exist they have an option to email them or chat to them and for you to speak to whom ever you must first insert your credit card number (obviously to **** more money from you) so I stopped the chat . Please help me get my money back
