Name Change - Family Premium

[Welkin_au]

When I decided to set up a family account it asked for name/street address etc and I entered the details for the first family member I was inviting and not my own details.

Is there a way to change the name to my own name?

This is NOT the profile name that you can change via profile details. I've tried everywhere and cant find a link to this address details (name/street/postcode etc)

Thanks
