Ultimately the op has asked their ISP to install a new service. It is now the ISPs responsibility to provide a working service upto a working NTE. The op does not have this hence clearly the ISP is responsible to get this going. Had the OP arrived into the property and severed the cabling they would be liable, in this event the cabling looks aged with wear + tear & there is no obvious damage by the op.
Additionally as part of a new line install, where a NTE master does not exist this is usually rectified free of charge. The op cannot officially go and install their own NTE hence it is BTs job.
Likely is the case the line is OK internally anyway, and they will get it going externally. We will see. Either way the NTE should be a point which clearly segments BTs side and the consumers side, the only chargeable category would ideally be deliberate or accidental damage e.g. cutting cable yourself or a builder damaging it, which the account holder authorised not the property owner 1 year ago.
