Cant cancel membership after trial; No simple or clear way to contact anyone.

I received an email stating that I did not have enough funds to cover the monthly charge for Adobe Stock. While I did grab some free images during the trial period, I found that they were too much of a hassle to convert formats for them to use for my purposes so I didn't use them nor did I come back to get the rest of what I was allotted and ended up forgetting about this account. I need to cancel it ASAP. Please fix this issue in the future as it really seems that once you have customers locked in with a free trial, you don't provide them with an easy or user-friendly way to cancel the membership should they end up not even using it as I did which kind of gives the impression that once we are members, we cannot cancel without jumping through several hoops. DO NOT CHARGE MY CARD. I do not want to redeem the rest of the images "owed" to me, I just want the account canceled.

Worst service I have experienced since my high school bully got a job at Best Buy!
