Standard Bank Credit Card RIDICULOUS process

I have had my Standard Bank credit card for over 20 years and have made MANY online purchases. Tried to make one today. Received an error message that the cell number I entered in order for the OTP to be sent to me was not linked to my profile. Same with my e-mail address. Called STD Bank, has to hold on forever to be transferred to their "Secure PIN Department" twice. Eventually Ashraf told me that the Secure PIN gets reset every 90 days and that I have to call them every 90 days to reactivate this (and that this has always been the process). AND asked me to hold on to be put through to the "secure PIN Department". Again. What utter bull****. My cell number and my e-mail address have been the same for over 20 years. My card is in good standing. So KOEBAAI Standard Bank. Your service is pathetic, your staff are obnoxious and you have actually done me a huge favour today by making me cut up a credit facility that I do not really need. Toodles!!
