Utter incompetence and ********** behavior

Second complaint, first complaint still not resolved. I have a gold credit card at discovery, I was sent a new credit card thinking it was just a mandatory new card as my old card was coming close to the expiry date. When I opened the package, I found it was a platinum credit card. Thinking it was just a new card on the same account, I activated it on the Discovery app. After activating, the account balanced showed I owe R950 on the card for 6 months bank fees with interest but all the bank fee transactions are dated on the same day. The card was for a separate transaction account I never requested and never had for the past 6 months. I have been on the phone for 59 minutes and no one seems to know what to do, utter incompetence for a company that brands themselves as better than the rest.
