Request manager action!

I requested a USD withdrawal on 8 Dec 2023 to be transferred to my USD Forex account with Discovery Bank. In over 5 weeks, they still can't get this simple account correct. Two failed swift payments. I had to leave on my international trip without these funds and it is costing me financially. the Standard Bank call center is pathetic... you get cut off and not much happens. The email way of communication is extremely slow if you get any response at all. I requested to speak to a manager to no response. What more must I do to get this transfer done?
