Documentation nightmare

This makes me sad writing this review, but I always been happy about the service I get from African bank, but I have apply for a 15% loan on days 3 days ago, I have submitted all relevant documents on my app only to be asked again for the documents over and over again, even after trying all the ways vie email, what's app and my internet banking, it will always come back and ask for the same document's. I have spoken to two consultants confirming they have received the correct documents and uploaded it to the review department and I don't need to upload more documents. Just now I got a sms asking me for documents again. I'm so dissatisfied bacause they did a credit check on me and I don't want to cancel and try another company, it will ruin my credit score. I don't know what to do?
