Currently, the only way to get Cooking Tale Cash is to purchase it with real currency from the Add Cash menu. You can also purchase packs that contain Cash, Coins and Boosters.
- Making sure that you have a strong internet connection before making a purchase.
- Waiting for a while after making a purchase even if you haven't received it. Sometimes if you try making a second purchase right after the uncredited purchase, the uncredited purchase goes through as if it has already been credited. Therefore, the game mechanics never credit the purchased Cash or Pack to your game. Because of that reason, it's better to wait for a couple of hours before making a second purchase after the uncredited purchase.
If the purchase is still not credited after the given time, you can contact the customer support and they'll help you with pleasure.
