Selfie registration for money app

I have been using money app from Nedbank ever since I opened an account. I am Queenett Bethanie a private Bank account holder. Three months ago I changed my device from Honor 90 to Honor 200. However I cloned everything from the old to the new phone before I cleaned the old one as I always do with my phones. In December I was in and out of the St George's Mall branch in Cape Town till todate because the system is rejecting my selfie registration due to someone who helped me and deleted my original selfie from my profile. I compliment my Banker and her colleagues who gave me assistance without complaining up to the branch manager. Everyone who assisted escalated the problem but there has been no solution and response was yesterday where an SMS indicated that I should change my username and password for they are not acceptable. Mind you these are the same credentials I am using to access my online banking with. Every time I register the selfie I would get a message indicating that my image is too bright. I have done the registration process with Honor 90, Honor 200 and my laptop. This made me to conclude that the problem cannot be with all the gadgets I have. I am putting on record that all my gadgets are new and not malfunctioning. Help me with this matter and I need compensation for all the inconvenience incurred. It is also not fair to pay in order to access my account whereas over R400 is deducted monthly for administration.
