Capitec and Bizmailer247.com *****sters

So I was told I should pay shipping fee of R39 for a phone, I paid that and no phone or sms again. Until last night a total of R766 without notification from Capitec telling me about this purchase and was taken from Bizmailer247.com. I was shocked and went to the bank this morning because there was no agreements or anything I have signed up for. The bank says it hasn't left the account yet however the chat Reverse it the called a different department who was on the line over 20mins to 30mins just to tell me stop the card and make a new one which I now was charged another R70 baring in mind I just lost R766 because my bank refused to reverse this. How safe are if your bank is not even assisting you? How can your money be safe with your bank if they not assisting you with these *****ulent activities. Guy please share this as this could happen to many others. I AM GOING TO CHANGE MY BANK. NO HELP FROM MY BANK!!!
