I’ve paid to have the ads removed but I’m still getting them. I have a recite and everything if the ads aren’t going to be removed I would like my money back

I downloaded this app to not only help me see how many days till the event but to remind me that the event is that day just in case. But even though my notifications are on it doesn’t tell me anything. It just adds more days till that event. And would not let me delete the event.
