Query: Unbelieveably slow service

I odered four items on the same date, on March 28th, two movies and two soundtracks, from four different sellers. I received the other three items in less than ten days from the order date, with no problems. When I checked on this item, I saw that they predicted they would not ship it before April 30. Today is April 30, I have not yet received it, and I am not impressed with this service. If the item was in inventory, I find it hard to believe that this seller is that much busier than the other three sellers, who managed to send out the item promptly. All items were paid with a credit card, so they werent waiting for payment to clear. I am not a satisfied customer.
