upgraded the wrong work space - can it be changed

[Ruby]

Hi. I've been trying to work out how to contact support but I don't have an atlassian URL so i guess i can't? 

I've recently upgraded my trello from free - standard, as me and my client use it. We were under the impression that we would be able to create unlimited boards. I've upgraded my workspace, instead of my clients. Am i able to transfer this to my clients workspace?

Thanks
