Dread

As the title says today I played a little bit. As I logged out I had a Haunter, I think he was Lvl 32 or something in my first teamspot. Later today I logged in again and my haunter got replaced by a Squirtle which was Lvl 5, like my starter was. I had my starter removed out of my team because I used Rattata for cut. Is there a way to get my Haunter back and the Squirtle removed from my Account, because I think its a little bit unfair to have to Starters (like dupped) and I EV-trained my Haunter aswell. If that is a common Bug and is not solvable, I might consider quitting this game of obvious Reasons....
