Application for Platinum Credit Card not done

I lodged a complaint last week with Standard Bank via this website. It took them 4 days to respond. I received feedback that the reason my online credit card application was declined was due to Platinum credit cards being offered to its Private Bank clients 'by invitation only'. I was told that the Product Manager would review my application. No feedback yet. If Platinum credit cards are not available for application by non Standard Bank clients (who meet all the criteria) then it should not be available for online application. The service from Standard Bank is slow, and a bad reflection of its customer service standards. The resolution manager agreed it had poor service and promised feedback. Where is the feedback?
