If you exchange Google Play Points for in-app items, in-app services, or Play Credit, you won’t get a refund. Google Play Points used to support a good cause aren’t refundable either.
If you exchange Google Play Points for a coupon and make a purchase with that coupon, you’re eligible to get the purchase refunded. If the refund is granted, you’ll get back any amount you paid with your form of payment and the points you used for the coupon. If you want a coupon, you’ll need to exchange points for another coupon, if available.
For purchases made with other forms of payment, learn what happens to Google Play Points if a purchase is refunded.
