You need to download a separate app from the website mainly for buying coins.
Sign up to foxtoon on your PC (use google translate on your browser page should help you along the way). Then download the foxtoon app, and as soon you enter your username / password on the app, you should be able to see their coin bundles and prices, you can pay using google play credit.
1 - Either use google play cards you can get these from stores in alot of countries so you can check your stores for availability.
2 - If you use a prepaid phone, you can recharge the amount to your phone, and when you purchase a coin bundle it will deduct that amount from your phone. (It will ask your confirmation and will convert the money to your currency before purchase)
Here, got a solution to your problem! :"D
