What device do you use?
If you use Android then you may try Lucky Patcher.

 

in order to purchase in app, you need to own either a debit card or credit card, input it to your google play account, it must have a balance in order for the transactions to be successful alternatively, you can always purchase iOS/Android currency here https://www.carddelivery.com/
