I had a very bad exprince iwth cancelling a trial add-on. (Leadbooster).

It was easy to add, but once I decided to end the trial (to not pay for the subscritpion), there is NO cancellation buttons or options.ย 

I looked all links and pages, and finally I had to contact the helpdesk .. that took too longtime before my trial was charges, until they showed me where to check mark and then move to CHECKOUT to cancel...ย 

Then I had a much longer problem to refund the charged subscription that I had no intention to use...

To avoid headache for other users, please consider to change your interface for add-on cancellation to be clearly visible to the first time visitors. Don't hide it as it is now, it will just create negative feedback.ย
