Pathetic Discovery Bank service

After many years of using a Discovery credit card that was linked to FNB, I had to renew the card with Discovery Bank at the end of August. I app**** for the card and tried to register as a client on the Discovery Bank app. The app informed that I was already a client. When I tried to log in as a client the app informed me that I was not a client. After 5 weeks of endless phone calls; empty promises and so-called escalations I still don't have new card and I don't have access to the money that is in my account. The total incompetency and lack of service is disgusting. When I wanted to close the account I was told that I would lose all my Discovery miles unless I exchanged them for cash. But guess what? I need the banking app to do that. This SUCKS!!!!!!!!!!!!!!!!
