where you on talk talk LLU ?
You do have sky and c &w llu providers in that exchange and a scheduled fttc roll out date in Dec12
Well if the ain't providing you with a service then they can't be expecting paying, infact i would think it very necky of em to even charge you , as indirectly it's plusnet who have failed you ,as openreach won't speak to you, as you are not their customer,plusnet is, if they are unable to deal with it maybe time to leave them, imo any contract should be null &void as they are unable to provide you a service
