Cancel My Adobe CC

I've done a month-month (1 year) full Adobe CC package  since June 2017. In May 2018 I switched my plan to a reduced Photography plan for the remainder of the 1 year subscription, however my subscription was restarted for another prepaid year. I was not notified that my current plan was being reset and that if I cancel now, I have to pay for the remainder 8 months cancellation fee.

This is unacceptable and I want the auto-renew to be cancelled immediately. My plan should not have auto-renewed after June 2018 but there is no option to disable it through my settings.
