Misleading product description + poor service

What tipped me to buy this product was the following description in the product overview: "Poet or songwriter? Rhymes & Syllables is only available here and will help any lyricist."

But its actually an in-app purchase. This is dishonest marketing. I contacted customer service about this, and got no response.
