I'm in a similar boat. I signed up for my Adobe CC membership over the phone, and was offered the free stock trial. The individual who signed me up actually signed me up for the 40 images a month version as he said I could download those and cancel and not be charged. I never ended up using the free trial, or using the Stock program at all. I went online to cancel after seeing the charge for the 2nd month which reminded me of the stock trial on the account, and was shocked to see a cancellation fee of $255. I signed up over the phone and was never informed that the trial membership would turn into a yearly commitment. I cannot afford the additional monthly fee for Adobe Stock, or the cancellation fee. I tried to speak to Rahul online through the chat and he only offered me 3 months free (which I took to provide myself more time to hopefully find another resolution) but this is a program I won't use in the future and would love to seek another solution to my problem. I feel deceived and misguided at the yearly commitment option seeing as how I signed up over the phone with no ability to read over the terms and conditions to discover these fine print obligations. Any help would be greatly appreciated.
