What is the best way to contact support?

Hello everyone,

I ordered a Fairphone and some accesories on July 11 and received it on July 13 but in the meantime I managed to repair my old phone so I don’t need a Fairphone anymore.

I would like to return my Fairphone but I can’t find any indication on the website, I have no answer to my emails or phone calls…

thanks for your help !
