I was charged more than the advertised price on two separate occasions?

This is a scam you cannot advance in the game or access any features without paying or waiting tremendous amounts of town or getting nothing at all I'd suggest get one that is totally free they're out there and this game was once too until they planted the seed to get you coming back then they put cost on everything and charge you whatever they think you will pay. Go on to the next free game they've made so you will not have to pay!
