NEDBANK CREDITCARD DIVISION LIKE HEADLESS CHICKEN

I recently received a call from Nedbank Credit Card sales offering me a credit card. The lady I spoke to emailed me as to documents required which I emailed to the email address provided in her email but had to do one document at time as the Nedbank card server only allows 2MB for attachments and received email read reports for all three mails. I received an SMS stating the card application was approved pending verification after which I received calls requesting the documents already sent and sent them again every time. Then an sms informing that application DECLINED INVALID DOCUMENTS submitted. I was promised an explanation as to the exact reason but nothing. My credit score was above 920 and now below due to the enquiry done and for what. The documents submitted are exactly the same as for my vehicles both approved but considered invalid by the card division. I didn't ask for the credit card they called me offering it then declined it not only wasting my time but negatively affecting my credit score of which I m most proud. HOW DO YOU OFFER A CARD APPROVE IT THEN DECLINE IT FOR DOCUMENTS THAT WERE ACCEPTED BY ANOTHER DIVISION OF THE SAME BANK. IT JUST DOES NOT MAKE ANY SENSE<br> <br>
