Hi, I'm Bhavik. Welcome to JustAnswer. I'm reviewing your question now, and will reply back ASAP.
When did you do these transaction ?
Below is the google's policy :-

For apps and games:
Note: you can only return an app or game for a refund once. If you buy it again you will not be able to get a refund.
For in-app items (including subscriptions)
Within 48 hours of purchase
Submit a refund request online. You’ll usually get a decision within 15 minutes, but it can take up to two business days.
If 48 hours has been passed then we will have to contact developers of app to get the refund.
Sooner we do it. Better results we will get.
