Unable to cancel Free trial period

So I have just activated free trial in Adobe. Still have some time to cancelt it but I can not. After choosing the reason of cancellation, there's this message on the next page: Unable to download data. Error occurred, try again

    And that's it! I've tried logging from different devices, browsers, but nothing worked, also I did not find any direct support page in which I could discuss that problem with real person. But I hope community will help. Is there anyone who had the same problem? Or how do I get to support team to solve this issue? Thank you in advance.
