********** online purchase

I'm not so happy with Capitec bank service concerning the ********** transaction that happened on my account on the 28 December 2018. Everytime when I make a follow up I'm told that the person investigating will call me. No one has called me so far. I was told that the investigation takes 8 to 14 days. I am so annoyed because I feel that they are not taking my query seriously. I don't think our money is secured with Capitec. I need them to contact me & refund my money.
