Hi @Alfie2019 and welcome to our adorable Community 😊 I am sorry this happened to you but don't worry, we can solve this together. Please follow the instructions on the link below and you will see several options what to do when your purchase goes wrong including the refund option.
I paid for coins to refill lives and boosters some of which were endless for an hour. I received 11 coins nothing else. I want a REFUND so I can delete this app forever.
