7 day trial

I cannot get the trial canceled.. I have tried everything. I then called the 1 800 help number and I was told if they canceled it for me, there would be a 49.99 cancellation fee!!!! They said I had to cancel on the app for free. It WILL not work from the app!!! This is a scam from YouTube!!!! My trial ends tomorrow...help!!
