Generally speaking, Google Play should render its decision within 24 hours and have your refund out to you within four business days. For unrecognized (fraudulent) purchases, it may take longer.

Head to this link to view the Google support page for Play Store refunds. At the bottom of the page, there is an option to contact Google directly. Tap it, and tell Google the reason you’re contacting them. Keep entering information and tapping the Next step button until you get to the end, where you can initiate a chat or email with Google.

For apps and games, you can get a direct refund in the Play Store within two hours of purchase. You can fill out a form up to 48 hours after purchase.

For books, TV shows, and movies, it’s seven days for most countries and up to 14 days for select countries. However, defective content can be refunded up to 65 days after purchase.

For audiobooks, all sales are final except in South Korea, where you get a seven-day window as long as you haven’t listened to the audiobook.
