I have 2 (of my 4) tickets on my account left to use. (I am in presale group Red Hill...trying for the St. Louis show.) I tried at 10 am this morning (and throughout the morning/afternoon) to get GA tickets at the Sept. 16 St Louis show. My presale code only "unlocked" the VIP tickets. I tried on my mac/Chrome, I tried on my Android phone, I tried logging in directly to TicketMaster (not using the link supplied to us). NO luck. I called TicketMaster...they tried my code, only "unlocked" the VIP tickets. TM ticket sales forwarded me to TM customer service, which blamed whoever issued the presal
