Going around in Circles

I cannot make online purchases using my credit card. I have tried with several suppliers and on several platforms. When on Payfast I get a message to call *** and when I do and after holding on for 45 min I am told that I must speak to the ***** Department as the error is risk based, then I get cut off when I am transferred. I then try and call them directly on *** and get told I must speak to the Risk Department on ***. This lasted 13 calls and 4.5 Hours.

I then called my Personal Banker as I am a prestige client and told her not to transfer me (her name was Gwen and she transferred me to the Risk Department, who again told me to speak to the ***** Department ....

I can make purchases using my debit card, but not my credit card and do not even receive the In App Notification when I try

This is taking "How can we help you" to an entirely new level of incompetence
