My vampire system. Rip off

I have been listening for a couple of months. Picking up free episodes here and there. Now to re listen to episodes I already unlocked by watching ads they want me to watch another 15 ads. Because I listen while driving. I can't sit there and press my phone on ads to cancel them. Worse still is the fact that it randomly switches to another book I don't know and haven't even started reading. I mean come on. Safety first. Fix the app or I won't be continuing the book. It's fine to have to watch a few ads to unlock the episode while not driving. But then to re lock them and make me have to watch more. Your kidding yourself. How greedy can you get. I'll say one last time. FIX IT.... or us consumers will move on.
