Bug

You will need to be a little more specific with your complaint if you want any feedback or advice on this. What do you mean by bugged, @julioindio ?

There are indeed many bugs in Candy Crush, the connection issues are quite long standing. As for the ads, I'm afraid King take those away from players who make a purchase with real money, because they hope once you pay you will continue to pay. There isn't much I can offer in way of help I'm afraid, but if you made a purchase and it has not arrived then do contact player support as they should reimburse you. The best way to do this via settings in the app (the cogwheel on your map screen). In all honesty I would never advise anyone to spend money on this game. The more you spend the more they expect you to spend.
