  5. [R4] BOSS Revolution 1/5 · US Money grab harassment: The app is on every step defaulting to monthly subscriptions. You are automatically opted in. I have had to cancel subscriptions I was tricked into multiple times. then when you go to cancel they also play tricks to obfuscate the cancellation process. @apple support can do a better review of this behavior.
  6. [R16] BOSS Revolution 1/5 · US Didn’t work: I downloaded this app and the $2.00 you get added to your account is useless. I tried to make 1 call & before I could make a call I had to add money to my account. So the $10 got charge to my credit card, but didn’t get added to my account. Beware!!
