This is definitely something I need to share! We switched to Simple quite some time ago. Once they knew we were multiple, and prefer to be treated like individuals, that's exactly how they treated us. Check out this screen shot of a conversation with support! They acknowledge there are 9 of us!
In most messages, they use the name of whichever one of us messages them.
On top of this fantastic level of respect from support, the bank itself is full of great features and hardly any fees. (We can even tag payments with our different names, to keep track of who's spending all our money on video games... such as Koda.)
I recommend every multiple give them a try!
