CVmaker Surprise Subscription Charge Refund Request

Last month I paid $1 for a résumé via CV Maker. However, this month — without any notification or my approval — another $8 was charged to my card. There is no membership or automatic renewal on my account, and I was never provided with any contract or notification regarding this. I am requesting a refund. The payment was made using my email address: o*********@gmail.com.
