I want to start a new farm but cannot. Please help!!!

I want to create a new farm on my device, I do have a new apple ID, I did delete Hayday in my divice, closed completely Hayday app, logged out my FB account, logged in the new ID in game centre. When I went to the game, it was my old farm and I carelessly press 'yes, keep the current game in new account'.
Please help me!!! How can I start the new one?:confused::confused::confused::confused:

You have to do a factory reset of your device because just deleting the game doesn't take it off the device. This can be tricky if you don't know what to do and I can't tell you because I don't want to tell you wrong. So maybe one of the others can tell you or maybe do a search on this forum. It's been answered before. Check the stickies at the top.
