A request to change my Sophos Partner E-mail.

Hello,

 

I'm having trouble to figure this by myself, I can't seem to get access to the live chat for some reason, the js script doesn't load, and I'm not sure that it is here that I'm supposed to ask but, I would like to change the e-mail address currently associated with my Sophos Parter account, how can I manage that?

 

Any help will be appreciated.

 

Thanks!
