Need initial help

I have one standard plan.  I need toi assign this seat to another person.  I cannot find ohow to do this without buying a second seat.

I try to a chat but I get no window that pops up.  

I can sign in but Is my accoutn not yet “activated”?

Do I have  to buy a support plan separately jsut to get basic login help?  

I can’t call or email on the support page yet I can login.  

Thanks for any assistance.
