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.

> I'm sure "purchase does not work at all" is an exception

Nope, a Play store "support specialist" just told me: "I tried to create a refund request but its not allowing to create one since the date of the transaction is out of our refund policy as we can only process refunds for up to 120 days only after the transaction was charged."
