Forza Support Ticket Error Message

Hello, for the last week whenever I try and submit a support ticket I am met with this error message:

403 Forbidden


The various support read me threads work fine, and I can fill out the ticket, but when I click submit I just receive the above error message. This has happened on three separate days this last week. Please can this be fixed ASAP because it is incredibly frustrating when most threads reporting bugs/game aspects not working properly are met with response of ‘Please submit a ticket’, but for me the ticket system just results in an error message!
