many thanks, I sincerely hope VM will be chased by (and will react properly to ) upstairs new neighbours', but I am mortified what will happen to my connections if this is left like this.
I am seriously considering in that worst case taking VM to court as I am running my own business and if my broadband cuts out due to their absolutely insane botch job, then I legally, too lose my sense of humour (any that is left after this...).
Even if they subcontracted it, they are responsible - the level of this "workmanship" still has me shaking and overnight we agreed with neighbours to at least try put a plastic bag somehow over it and protect the connections from weather as much as possible
