Forgot to check out how to cancel subscriptions when I signed up. Had the same experience with The Australian. Had to ring a phone number in Sydney to cancel.
The New York Times had an 0800 in New Zealand but not satisfactory. Had to send an email to the Financial Times because its website gave no information on how to cancel.
The Economist is even dodgier. I had a look at my initial subscription email to find out any information on how to cancel. My account at their website provided no information on how to cancel.
Any online service that does not provide an online cancellation option is dodgy. No excuses.
