não consigo cancelar o adobe stock, aparece que meus dados não foram encontrados, o que eu faço?

Let us know if @Jill_C 's instructions did give you the solution. Sometimes it also helps to wait a day or two. As it is now weekend, chat will anyhow not be available for in-person support. I would try again to cancel on Monday, if that does not work, I would use the chat then.
