Purism’s stated policy is that it refunds orders when it gets to your order in the queue. At this point, Purism should have gotten to your order in the queue, so you have a legitimate complaint, and you should publicize that fact on public forums.
As I said before, I am hopeful that Purism’s recent fund-raising means that Purism will be able to repay cancelled orders for the L14 and L5, so this situation can be resolved. @Benko did eventually get his refund after many months.
