Im sorry to hear you’re having trouble cancelling your subscribtion. In order to switch from Premium to regular you must, follow the link provided to cancel your Premium subscribtion. Hope this helped :)
Just wanted to add that if you don't have the option to cancel, it might be that you are logging into the wrong account. Perhaps a friend or family members account or maybe you have a second account with us you do not know about.
You can use this page to find any extra accounts you might have.
Hope it helps! Let us know if you have further questions.
Have a nice day.
