Credit card application a mess

I app**** for a credit card online a week ago and sent all the documents required, I received an email saying I am approved but they need a certified copy of id which I sent and they confirmed receipt. What frustrates me the most is now I have received 3 more emails saying that my application is not processed because they don't have a certified copy of my ID and I have called and told they have it but after calling they send an email saying they don't have it hence application is on hold.it is really frustrating and unprofessional of a reputable bank like absa to mess up an application.
