Query: Do not buy for sound quality

I purchased this toy to teach my child letters and numbers. The toy was great in the store but when I purchased it and took out the "display only" plastic piece, the sound quality decreased 75%. I tried replacing batteries and putting the plastic discard piece back in but nothing worked. I finally called the company and spoke to someone who informed me that the toy had to be set to a certain decibal. I told her I could barely hear ANYTHING (I had to put my ear up to the phone) and that the sound decreased so much from the time I bought it in the store. Long story short, I believe this item is FALSELY ADVERTISED. I threw the toy away as soon as I got home!!!!
