UPS - Vox - NON service

I purchased a UPS from Vox over a month ago. It comes with no instructions. I’ve tried to set it up and it’s not working. I have requested 3 times that someone from vox comes out to set it up as I am paying for something I can not use. I was told on 3 occasions someone will come out and set it up. Just for me to postpone appointments and wait and no one calls or comes around. I tried calling the help desk or technical dept where I am on hold for hours . When I request a call back someone calls me hours and hours later , promises to send someone around and then … nothing. Possibly if Vox is sooo busy they need to employ more people to answer their phones. I have only been with Vox for 3 months and so far very unhappy with their NON service !
