I subscribed to 10 standard assets a month but after three weeks it turned out I won't need it so I wanted to cancel.
Problem is I was not able to do so, because in Chrome on Mac plans` management section of my profile literally doesn't work - I'm getting the blank page (see an attachment below). I tried to contact with support on chat, but as you can guess nobody was able to help me there. I was left alone with no any answer. Wrapping this all up - my plan has been automatically extended to the year subscription and I literally lost ~400 Euro, because I got something which I don't need and will not use.
Sorry for a delay in response. I have checked your account details and noticed that your Adobe Stock subscription has been cancelled and also the refund has been credited to your account.
Feel free to update this thread in case of any additional questions.
