Please tell me how can I stop you charge my money. – Logo Maker - poster Creator Review

This app is so horrible. I just download to see how it work and after that I deleted it from my setting because it’s not work for me, but they’re continue to charge my money months and months. Please let me know how to stop it, and how I can bring my money back to me. Thanks.
