I bought an support extension plan for Hermosa theme but was never able to use it

Hello,
I bought an support extension plan for the Hermosa theme (Noo theme). I couldn’t use it so far because when I connect to the support forum it says ‘‘account not valid’’. I’ve tried to talk to the Noo support team but I have never been able to get some help.
Please advise,
Thank you,
Olivier
