Discovery bank just lost a customer

Discovery Bank just lost a customer. I opened a Pay as you Transact account on Friday which was relatively easy on the app. However on Saturday I wanted to upgrade to the Black suite - I contacted them and had to them contact them again on Monday - in which they gave me quite the run around. Eventually I was told, I cannot upgrade until I close my current account which would take up to 8 working days and only then can I apply for an upgrade to the black suite. Completely unnecessary and very admin intense. I’ll be sticking to my current bank and never trying out Discovery bank again.
