FNB mess up again

This has to be the worst service I receive from this bank, I mean I have had some hurdles with them before and yes they were really bad but this tops it. How can I not get feedback on my application and when I enquire I am told the documents I submitted were not clear lol, the same documents I recently used to apply for my account days apart to the same email address, I am busy chatting with Annette from the Credit Card fulfilment department and all of a sudden she tells me that the lending criteria has changed, never mind the docs not being clear for her now there are additional documents required and I must send them to a different email address and wait another 48 hours, what joke is this? Why do you guys do these things to your clients?
