Discov***3ery bank credit card issues

Discovery bank paused my secondary card without notice nor contacting me. Pathetic customer service. Note that My account is fully paid up no arrears. Its gets even worse - I am a purple card holder. Disgusting modus operandi!!!!. I have made calls & been on hold for ages, only to be told that the manager will call me back but no response. So much effort is put into designing products and discounts and cash backs but basic courtesy is ZERO!!!! NOT WORTH SUPPORTING THIS BANK!!!!
