Our friend has a shop in Nelson CBD, today they moved into a new shop and are having issues with their phone connection. Prior to the chorus being sent the electricians had been around and relocate the phone jack, they left saying the internal wiring was good to go ready for the connection. Today after being connected the phone line is unusable with the constant beeping tone, the tone after someone has hung up on you. 

Someone from Vodafone rang and left a message on friends mobile saying Chorus had connected the line and checked it was working at the patch panel in the building, basically the guy said it was an internal wiring issue that they are not responsible for, which if that were the case we understand.

As there is a beeping tone on the phone does that still mean there is a wiring issue from the panel to the jack? Or has vodafone/chorus made a mistake on their end?
