DISCOVERY BANK DISGUSTING SERVICE

This is the worst service I have ever experienced. Discovery moved my credit card from FNB to themselves without my approval or consent. They then told me my new credit card would be delivered Friday 29th May, then Tuesday 2nd June. Call reference *** - and I get told that I must call Discovery's outsourced courier service to track my own credit card. DISCOVERY YOUR SERVICE IN THIS REGARD AND YOUR LACK OF COMMUNICATION ABOUT MY CREDIT CARD = THE WORST SERVICE I HAVE EVER EXPERIENCED. YOU WILL NOT CHARGE ME INTEREST. Why must I track my credit card that YOU are delivering to me? Disgusting. I have been told I must sort out myself and call DSV courier services - are you for real?
