I doubt they were hoping you didn't notice brother. I will tell you the same thing I've told many people here about a small over site that several people don't read on their website.
It says that if the items you ordered are not in stock they can substitute your items with similar items from their stock. They can, have, and will do this at times. Is it right? Not to me no. But it is stated that they do this.
I will try and help you out anyway that I can brother. Naps-Support has been decent at working with issues I have brought up to him. So let's see what they have to say.
I'm not promising anything here though. I'll just try and help if I can.
