Frustrating to apply for credit card

Nedbank contacted me for a credit card application. I needed to supply documents. Eventually I went into the bank to hand them the documents and a new application was completed. After several days I received feedback that my application was rejected as I could not supply them with a marital certificate.. what a joke as I was never married before and nowhere on the application did it state that I was married.. in fact it showed single. A new application had to be done for the 3rd time. It has now been a week since the new application and still no results. I am the one that needs to phone and follow up as the agent at the bank only keep on saying the application is still pending and not sure what is happening. If we start this way I am not sure how we are going to end. Not sure if I really want to do business with Nedbank anymore. This is frustrating. Think I should rather move to FNB or someone else.
