I've never succeeded on getting a refund with Google. There were a few apps that tricked me into buying a subscription (namely Musescore and Yazio), I immediately asked Google for a refund because I didn't actually get what I thought I was getting, and they denied me both times.
Now I just don't buy anything on the Play store that I can't afford to just be outright scammed on.
