Discovery Banks pre-approval process cost me!

What a mission to try and apply for 'pre-approved credit!' My phone doesn't have the app and can't be upgraded to download it, so the attendant tells me I can download the app on someone else's phone, upload all the necessary documents and then delete the app! NO SO!! you need the app on the phone to do ANYTHING, even just check in to see how far your application is. They don't ask for everything all at once, its bits and pieces of info. No one can really help you, everything is 'private' through the app. Its taken me over a week just to try apply for credit to buy transport and in the meantime I've lost the transport. If this is a sign of how they do business, they can forget it. **** service, application and assistance all round.
