Dissapointment from credit department

So I app**** for nedbank credit card online,was pre approved.i was told to send my docs to the email that they provided *** after a day same message came to my phone again telling me to send my docs,this time I forwarded the documents 6times,I'm writing today at this moment I'm still told to send my documents to finalize the application,do this people know how much money I'm loosing to resend this documents everyday,I tried phoning them one consultant told me I only submitted April statement,how come because this documents were send under 1email?I'm so disappointed with the nedbank
