Useless service

I signed up for a new fibre line with vox last month and open serve came out to install the line into my house, I called vox to request the router be sent as open serve has connected the line to my house. I been sent from pillar to post everytime I call them, everyday its the same thing issue is being escalated to the project manager, last week I was promised that I would have the router by friday its monday again when I called them they gave me the same excuse of the project manager. I requested to cancel the contract as I don't have any of their devices or used their line and they saying the is a cancellation fee. I don't advise anyone to take up a contract with them, their consultants are rude and unprofessional
