Impossible to add new credit card as billing method

<p>Six months ago I was forced to call in to change my payment details. Now, because of *****, I'm forced to do the same.</p> <p>Please don't offer an online feature if it doesn't work. Every time I add the card, I go through the OTP process, it takes R1 off my card, but the card still doesn't reflect on my account.</p> <p> </p> <p>What's more, when I requested a call back at 11.30am today, I was only contacted at 7pm. It just so happens that your account department doesn't work at 7pm. Last time I had to give sensitive card information like my CVV over the phone which is just not on (and not PCI compliant - perhaps I should let my bank know?)</p>
