Got Some Subscribers but lost too – Subscribers tracker for yt sub Review

I have subscribed to a lot of channels to earn coins. I was so much happy I had 350 subscribers. But how come it reduced to 165 within an hour. How do I know who unsubscribed to my channel? Please help dear team. I thought this app will take action against those people who unsubscribe to the channels for those channels they were paid coins.
