Has anyone else had ongoing problems with their phone line going dead?

I have had to call out BT twice in two weeks due to this and they have told me on both times that the problem is due to someone putting their stuff in the cupboard in the basement in Institute Place. Next time they will charge me for the call out if it happens again.

Does anyone know who has access to this and using it as their own personal storage cupboard?

 

Thanks

Stephen
