more than 7 working days and still no response

When i was offered to move to Platinum banking with FNB, I was informed about \Premier"banking and how much better the perks were. After sending my documents in more than 7 working days ago. I still haven't heard a response from the credit department regarding my application. I sent all the necessary docs more than a week ago and was told the turn around time was 3 to 7 working days. I have to continuously follow up on my case"
