A couple of years back my local box was vandalised loosing me my connection as the cables were ripped out. I rang CS and was told they couldn't do any about it unless they got three calls from people who said they had lost their connection to!!! - unbelievable.
I tried the the H & S angle and quieried the possibility that the other prople who used that box might be on holiday for 2 weeks. Would that mean I would be disconnected for two weeks? But they wouldn't have any of it to begin with. I think they relented in the end through my persistance.
I made a post about it on the old site and a very nice NTL local manager gave me his number to ring to discuss the incident. What a nice man, a very nice man
