Bad Service from Standard Bank

I received an SMS of a Purchase made on my card on Saturday 22nd of June 2024 and I never approved this purchase as I was driving and when I got home called Std Bank Credit Card ***** division to stop my card. The card was stopped and a New Card was requested and delivered. One month later another transaction comes through on my card (which is a NEW Card) number for the same amount. Daily late at night around 23:44 - 02:00 i get an SMS as follows: Standard Bank: Dear Client we are investigating your ***** case 2024-??????????; Thank you for your patience. We will contact you as soon as investigation is complete. Today another transaction is made again and rep**** to SMS n to the ***** STD Bank ***** Number which they called me to BLOCK the card, and transferred me to the ***** dept waited an hour no one answers. I really would like to know how long does it take to clear this from my account, as I notified the ***** division that I did not make this purchase and when will this amount be reversed from my account. I've been a client with Standard Bank for more than 30 years and their service is just getting worst by the day. They a month later still have not concluded the case.
