Help to cancel my subscription

I am trying since 3 days to cancel my subscription to adobe but I end up in a circle, because it is still not manageble from my profile. In 3 days the trial will expire and I feel trapped. I tried to find a customer service but when I select contact us button, I am rerouted again on the manage your plan, which is still not available in my profile. I coudn't expect all this. Decepted by this politics.
