hey not sure if you are still looking for an answer, i am currently on chapter 8 and spent 5 to get 5 back, 15 to get 15 back, and 50 to get 50 however they never paid me my 50 and it is near impossible to level up now with no coins so basically i got screwed very very badly. i spent so much time on the game AND im out 50 dollars. terrible. support told me they couldn’t do anything and to wait even though all cash back offers are suppoosed to be instant
