Created adobe stock account on an email that was not mine

Hi I have recently created an adobe stock account, I was asked for my email and card details, no password. I created the account and went onto download the images however when I logged in the free trial. When it came to logging back in I did not have an adobe stock account. I believe I have entered the wrong email when making the account and now have this linked to my card and will be charged when the trial is over. I have no way to cancel this as the email is not mine/ in my possession.
