Were you required to call to cancel your subscription with Constant Contact?
California has a strong law requiring that subscriptions are easy to cancel. If you signed up online, you should be able to cancel online.
It appears that Constant Contact permits you to sign up online, but does not let you cancel online. Did this happen to you?
Javitch Law is currently investigating companies whose subscriptions are difficult to understand and cancel. Please contact us to alert us of a violation.
