Poor customer service. Used app a number of years ago with significant $$ investment. When I came back to the app my entire collection was missing. After months of going back and forth Bunt offered me about 10% of the money I had lost as compensation and patted me on the head, all while offering absolutely no explanation as to how they arrived at this settlement or what happened to my old cards. Takes days sometimes for response. Play for free, don't buy diamonds. Thank me later.
