Impossible to upgrade bank account

Hey Discovery Bank, Do you actually want customers? So I've been trying to upgrade my Discovery Bank from Gold to Black. Well, first time in my life I want to give a firm money and they decline it!! I was told that people with no prior credit limit with the company are not eligible to get a credit card at this point. And your consultant can't tell me when this will be possible. Seriously?? Funny since your consultant told me to get the Gold Card as a bridge to get the credit card. I meet all the criteria (salary, etc.) and also have my medical aid and car insurance with Discovery. Please urgently assist or will just have to close it down. No point for me to pay fees for nothing! Looking forward to being professionally assisted!
