I have two candycrush accounts and the data on them got switched.

One is for my friend and one is for myself. I was playing on my phone up to a certain level without being logged in, so when I went to go on my friend's account, it automatically thought my friend was up to my level and erased his progress. Please Help

Once this has happened there is nothing you can do I'm afraid. The game is designed to read the level progress so once its been written over then I don't think you can set it back. Sorry to say it!
