Charged for a ended trial, I canceled the plan but got a 60 day Trial. I am still charged

Look into the conditions. I think it's more as Just Shoot Me says. As I don't cancel I do not see that option, but it may well be that you are commiting for a 12 month subscription but pay only for 10. If it's labeled "trial extention", however, it may well be an extended trial, but that would make less sense in a commercial way.

No by accepting that Free Extension you actually Sign Up for the Full year. Either + the extension or minus 2 months of payments

Please Remember this Nothing In Life Is FREE. Somebody, Someplace is paying for what you think you got for Free. In this case it is YOU that is paying for those 60 days Free. So it Ain't Free.

That is a free EXTENSION to your paid subscription, you still need to cancel at the end of the extension
