Quit stealing my coins !

Just opened the app and had 16 coins taken away! I've started monitoring my coins every time I use the app and it's happening at least 3 times a week. No wonder it's so hard to get them to add up. Ive had this app for 3 years now and it just progressively getting worse. I think it time to find a new one. I've tried complaining and they don't even acknowledge me. I'm so over it! Watch your coins guys!!!
