poor service

On Tuesday I app**** for a credit card, was told that the process takes about three days on the 13th of may I went to th centurion branch we I was told that the application was incomplete due to the document that I didn't send do they said. But when the consult who was assisting me checked he realised that the docs were sent but not actioned on the telephone banking side. I therefore requested the branch to do another application for me which was done. On Friday I called the number credit. Card department and was told they have backlogs therefore my application has not been finalised, I don't understand why the fnb service is poor compare to other banks when it comes to credit cards, I'm fed up no feedback has been given since then even though the account has been loaded under my account on online banking
