refund

I did not realize that my free trial had ended today Oct 3th and was converted into a paid subscription today. I noticed the Google pay charge today. For information, I subscribed the plan on Sep 26th, and just cancelled the whole plan today on Oct 3th. 

I cancelled my plan through Google Play Store app.

I wanted to refund.... Can I get refund???
