do not use and want to cancel adobe stock, followed support and there is no help, I am at the end of a free trial that i did not use?

How do I cancel?  There is no direct contact. I went for the free trial thinking of it as a stock investment. It is not what I thought, and I do not need or have any use for creativity like this. There is no switch plan option for me. No cancel option available, no direct help.
