You can't - that's a large part of the frustration here. Customer service people appear to have no direct conection to whatever department is sending out the phones. Some will tell you date (tomorrow, three days, etc.) but these seem more made up than real.
Just talking on webchat, they say stock is back, and is doing allocation in the next 24 hours.
Compensation okay, i said i could've called in earlier, but your sales number said "wait we'll call you don't call us", and because of that i didn't continue, because i think that pre-order means something... right? right??? WRONG. And i calmly explained that i could've got the order NOW, but because your Optus phone says don't call us about the iPhone X, then I didn't
Lols who knows that did delay me!!!, next time (if there is a NEXT TIME), i'll just call in ASAP to confirm my order, because pre-order sequence means NOTHING.
