How do you apdate a support tiket?

just compiled a tiket for a major account problem that got just solved by itself after a few minutes (registration code was flagged as already used for the first 5 try on the mog station that just suddenly got accepted after 3 more try (done after the support request)

How can I edit my support request in order to close the tiket? (in other game sometime u get your account blocked for problem like those until they end with their investigation and since the problem is no more it will just be a waste of my game time ^^') I searched the support page but can't find a way to do it... if it is a thing really easy to find... sorry for being blind ^^'
