No more preorders. The only way to speak to them. You don't order with a retailer or reseller, Hot Toys then gets less demand and purchases from them.
This will turn down the over production of figures that's saturating the market, leading to quicker release times or forcing them. If that doesn't work, maybe it will allow competition to pick up the Disney license as well. It all starts with us. Cancelling preorders doesn't help any, it only hurts the retailers and resellers because they already placed the order with Hot Toys.
