******** internet deductions on my credit card

On the 07/07/2019, Sunday night there was 2 amounts that was ********ly going off on my Credit Card. I contacted Capitec immediately and they stop my credit card. I told them that the money must be reverse back to into my account. Capitec advised me that they will investigate the situation and it will take 7 - 14 working days and someone will come back to me, they give me a Ref number. On the 13/07/2019 I went to a Capitec Branch in Port Elizabeth, Walmer and they give me a new Credit Card. After the 14 working days on 26 July 2019 I contacted the Bank again and they advised the case was referred for investigation to Mellisa and she will contact me. Nobody contact me. Again I contacted the bank and they confirm there is a backlog and still investigation the case and someone will come back to me. Today it is the 13th of August 2019 and no one has ever came back to me with the feedback. On the 7th July 2019, 26th July 2019, 31st July 2019, 2nd August 2019 and on the 8th August 2019 I called them and they told me every time they are busy with the investigation and they told me that they will sent an e-mail to Mellisa and they will tell her to call me back, since then I have been waiting for a call. Please help me.
