If you were charged by our service more than once for an event promotion then you purchased a subscription package to promote multiple events. If you only intended to promote one event then you likely do not need a subscription. See here for help cancelling your Subscription Package.
For any new event, you will be presented with an option to promote the event online using Evvnt's network of event calendars. You will be presented with two options, (1) a "Single" promotion for one event and (2) a "Subscription" offer to promote 4 or more events each month. When "Subscription" is selected then a subscription period begins at the time of purchase.
