I spent a crap ton during IroYachiyo banner (beginning of August) and requested refunds from then to now. The play store approved my requests. I suggest you do it too just to get your money back.

Edit: Only purchases made in August will be approved. I tried for earlier ones and they didn't approve them. Overnight, Paypal sent me emails about my refund, so you will be getting your money back

Edit: The process on how to do so (Google play):

https://support.google.com/googleplay/answer/2479637?hl=en

1. On your computer, go to play.google.com/store/account.

2. Click Order History.

3. Find the order you want to return.

4. Select Request a refund or Report a problem and choose the option that describes your situation.

5. Complete the form and note that you'd like a refund.

   1. I did both 'I no longer what this purchase' and 'Purchase is defective or doesn't work as advertised'

   2. Copy and paste below into form if you want:

      1. Hello, the game announced its closure today (8/28) without prior notice. I want my refund back due to this issue. Thanks.

6. You'll get a message that says "Thank you for sharing your concerns." You'll then get an email with your refund decision. You’ll usually get this within 15 minutes but it can take up to 4 business days.

Note:

• If you have multiple refund requests, repeat these steps for each thing you bought.

I've ACCIDENTALLY subscribed an app, mistakenly thought it was a free trial and was charged right way. I immediately contact google for refund and it is now under review. For common cases like that, will i actually get a refund for the accidental subscription
