the data kit that was installed isnt working.
There is nothing special about that. All it is an Ethernet cable that runs from the HH3 to a socket into which you can plug a lead to connect to a computer, etc. Can you be a little more explicit other than "isn't working", please? Details? Observations? Please describe your LAN configuration.
Could you move a computer (temporarily) to be adjacent to the HH3 and then test with an Ethernet fly-lead direct to the HH3?
If you are absolutely sure that part of the installed equipment is defective / not working, then get back to your ISP and insist that they arrange an OR engineering visit to correct the defective install.
