You may cancel your free trial at any time during the trial period. If you fail to cancel before the end of the 30-day trial period, you will commence a Club Catch monthly subscription that will be charged to your account.
If you have received a $6.50 charge this would mean that you have failed to cancel your membership during the trial period which has commenced the paid membership.
