To Slow to delayed no updates

I ordered my stuff from stake alot it been 4 days still not saying order has been shipped. I did an order with the pay just now option I'm guessing because of that they delaying my order. Thats so unfair. When I click why the wait apparently they waiting for a product. But like we order stuff from there because it's their available to order. If I knew it was going to take so long I would of ordered from somewhere else. Why advertise products that you have no stock off
