I am being charged €150 to cancel. I cancelled months ago because I couldnt afford it.

if, few months ago, you canceled an annual plan after the trial period, you can expect a penalty (=1/2 the cost of the remaining months) for early termination of that plan.

you can contact adobe support and plead your case. there are 3 ways to contact adobe; chat, phone and twitter:

chat:
use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

phone:

twitter:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam, https://community.adobe.com/t5/using-the-community-discussions/staying-safe-in-the-adobe-support-community/td-p/12919684/redirect_from_archived_page/true

When you cancelled before, is it possible that Adobe offered you instead some free time (perhaps 60 days), and that you accepted this offer (instead of cancelling, this is not a free bonus for cancelling)?
