@TeamYouTube I signed up for Premium Youtube free trial on July 31, 2018. A few minutes later I cancelled. Please refund "use of Google Premium" and use of Google Premium for reversal or correction of previous transaction." total of $2. It's supposed to be a free trial.
Thanks for reaching out, our YouTube purchase support team can dive into this further with you, contact them here: https://goo.gl/iXWSsc . Hope this gets resolved!
