Can’t get into tado

I was connected to my tado at my lodge my son in law did it whilst staying there all worked fine til he went home to his mums and logged onto her tado next thing is I’m logged onto her tado and neither one of us can access the lodge now his mums partner kicked us both off so I’m not sure what is happening every time I open tado it says I must be invited my email but my son in law gets the same thing can I delete everything and start again ???
