Faulty subscription – MyTopFollowers Social Tracker Review

I signed up for the free 7 day subscription and sent an email through the app to cancel before the 7 days was up. I have had this app for about 6 weeks now and get an invoice every week from iTunes charging my card weekly for this subscription which I canceled before the trial period was up. I've sent numerous emails requesting this be rectified but do not get a reply.
