appalling service

i am disappointed and disgusted with the level of service i have recieved from vox thus far, i have placed a order for fibre on the 5th of February and they have come on the 23rd in between that time they have cancelled on me twice for installation , on friday they finished up at 11.15pm which i didnt mind as my previous network has been cancelled that day and i had no internet, they had advised that once i get my welcome email i can login but since saturday nothing, email came and all passwords to the router is invalid and im only picking the serial number as wifi name instead of vox fibre , so i called in and had been on the phone for hours with no joy ,just transferring and saying they will call me back and advise but nothing , i honestly feel like ripping out everything of my property and throwing it on the side of the road , i should have never signed up if i knew this would be the problem
