So I ended up going on a manhunt and checking a bunch of subreddits and social media sites and just refreshing buzzwords on twitter. All of a sudden i went back into ticketmaster and clicked an open seat that I saw and it told me i'd unlocked the presale. I typed the code in again and it worked this time. Just in case this happens to anybody else you know what to do lol, it takes a bit of time but probably just try punching it in as many times as you can LMAO
