Tickets LA - Finals

Hi, everyone I'm looking for some tickets because the system that Riot Select didn´t work for me :( Don't know why but I was inside the ticket selection after the waiting room but I was not able to pick any section even with a lot of available places.

The map was fully loaded. Tickets were available everywhere and yet I couldn't get 3. The tickets evaporated in front of me u.u

I don't know why Riot choose AXS instead of ticketmaster like with the other games of the World Championship :(

Can somebody help me?

Pls :(
