So I got a code from a friend about a reward for a game I play so I download this app, and I sign up and stuff and then I get the part where you are able to put in the code right after you sign up so I go to look at the code I get it and then I go back to this app and then just kick me to the main screen so I can't even put it in. So then I find out where to put in the code and after it says that my future is full of coins but it doesn't even give me any and I can't even log in anymore. Scam????
