Got one ticket open (my first ticket at Sep 10 2008 was deleted from Stardock, dont know why?)
If you open multiple tickets on the same subject, all but one will be merged or closed; also, trying to 'bump' your ticket will actually result in the opposite effect (delaying response) as the queue sorts by least recent activity first. There is no need to spam support; normal turnaround is up to two business days.
In any case, I'd suspect that as you have one regular purchase and one preorder, the preorder is holding up the entire order. Sales will likely need to cancel it and you'll be able to order them separately, so that the Sins purchase goes through immediately (preorders are not charged until beta/release).
