I am very disappointed

My troubles started the day I decided to apply for a new home loan with my bank. Little did I know that I will end up having to spend more than R500 on scanning and Re sending offer to purchase to Nedbank more than 6 times with each time they will tell me I need to amend something on the offer which they never said anything about before after more than a week of resending documents to nedbank and running up and down getting the seller to update the offer to purchase and give me more documents required by nedbank bear in mind this is again time and petrol spent they decide to tell me that I have been declined and the reason is what AFFORDABILITY and why did you make me scan and resend the offer to you 6times
