Hello @melbuetow, Hearty Welcome to the Pet Rescue section of our friendly King Community
I am very sorry to hear that you have lost all the boosters!! Unfortunately that is the side effect that occurs when we change our devices OR reinstall the game!! I am sorry to say that these boosters are not refundable UNLESS you have bought them with real money!!
Hope this made sense!! Sorry for not giving you a good news!!
Thank you for posting in the Community! Have a great rest of the week!
