Paid for an Episode, it Played Wrong Episode

My 3 yr old son, Noah, loves the show Super Wings, and he loves dinosaurs. Well, tonight we discovered that there’s an episode of Super Wings called NOAH’S Dinosaur Eggs, so I purchased the episode because it wasn’t free, and then that wasn’t the episode that played! I paid for Season 4 Episode 10 “Noah’s Dinosaur Eggs,” and then it played an episode called “The Muddier the Merrier” instead. Obviously, my 3 yr old was disappointed, and couldn’t understand.
