Premium banking has worse service than student banking

I recently decided to upgrade my gold value bundle to premium banking. I app**** online and was given provisional approval. As it qmwas out of business hours, I was instructed to email my documents to ********** za. I did so. After more than 3 days, I phoned the premium banking number to find out what happened to my application. First I was promised a call back within 15min, which didn't happen for more than 3 hours. When phoning again, and speaking to someone else, I was eventually phoned back by what I gather is the banker assigned to my application. My documents were never even forwarded to someone to be assessed since 3 days back. I was made promises of escalations and resolutions. After 2 working days I phoned again, and was told that I should give them time. After now more than a week. My Gold Value bundle was approved in 15 minutes. Again nothing happened. Another 3 working days later when phoning again, I was told that the premium service is approved. No notification, an sms was supposed to be sent but the banker could not see on the system that this was done. I had to ask about next steps of obtaining the new card etc, I was told I will be contacted about delivery of my new card. It is now another 3 working days later and I am still waiting. And this is what you call your premium banking? I wanted to finance a car through this service but now I am finally considering moving banks. Other banks give me better interest rates and better service for sure.
