Query: nothing in package but the exercise ball

Once I opened the package, I realized that the only thing in there was the ball itself. It was supposed to also include an air compressor adapter, inflation plugs, and a plug remover. However, I did not open the package until a month or so after receiving it so I cannot return it now. It was my fault for trusting that everything I needed was in there. Now, I cannot use the ball now since I cannot inflate it! Be wary and take my advice: do not trust that everything is in the package. Open it immediately so you can return it if need be.
