ive had a problem no one can solve or wants too it seems like. Started playing as a guest and spent hundreds of dollars on this game. At the time signing in as a guest i was not given the options for linking the account to anything. Not facebook or gamecenter. Now, i still have to sign in as guest to play on my account. I tried signing in through facebook and gamecenter and login id and password, each time it started a new account for me and didnt actually sign me in on my account that i use. thats the problem, the only access i have to playing is through a backup of my ios phone, otherwise im screwed!!! This company give the term customer service a bad name. The replies are short and broken english and sometimes just dont make sense. its been about 2 months since ive tried to find a solution through them going back and forth. i play every day since i started and would like to play on my other ios device but i do not have the login/password, Because there is none! i need one! im on a guest account! They did not have gamecenter then on the app. In short they need to migrate my whole account to one that has a login information and a password so that i could use on i dont know possibly a new phone someday or another device. Its ios to ios if your wondering.
