How you can ask Assistant for a Play Store refund, but you must be using US English to make it work.
Here’s what Google Support says to get the refund:
- Cancel my Google Play app order
- I want a Google Play refund.
- I need a refund from Google Play.
- How do I get a refund from Google Play
- I paid for an app, but I want a refund.
Once you initiate the process, Assistant should show your most recent orders and ask if you wish to cancel them. But with all technology, it doesn’t always work. Try it out for yourself and see if you get consistent results.
