I had went to preseason with a team and gave them my details but never signed! They changed training nights so I couldn't commit anymore. I'm now trying to sign for another team and I can't as they have registered me! I've contacted the manager twice and he won't get back to me! I'm stuck in limbo!

To be registered for a club you should have signed a registration form. If you have been registered by a club who have forged your signature you should take it up with the League or Association involved.
