That link didn't work for me just kept taking me back to 'cancel annual subscription ' part. This seems quite a task just to cancel. I have never used it and don't intend to therefore I don't want to pay for something I will never use.
I want to know that after opening the above link, Did you clicked on the Big blue button labeled as "Still need help? Contact us" ? You will be directed for Phone support or Live chat support using that Blue button, on the page associated with the Link i provided to you.
