I can't trust Nedbank with my money

I recently went into Nedbank George to change the email address to which statements for Heatherlands Cove Body Corporate should be sent but Lo! and Behold! this has not been done. Previously I tried for TWO YEARS to change the postal address to which they should be sent and in the end I just requested them to email them to me. NOTE: I used to be the treasurer but I left Heatherlands Cove 2 years ago and my name was removed as treasurer. I was considering investing some money with Nedbank but if they can't even get a simple task like changing an address right how can I trust them with my money?
