In the VM Connect app if you touch the letter above your name it will take you to a "My account" page where there's a pencil(ish) looking thing in the top right corner, that lets you change your name.

I do not work for VM, but I would. It is just a Job.
Most things I say I make up and sometimes it's useful, don't be mean if it's wrong.
I would also make websites for them, because the job never seems to require the website to work.
