VOX telecoms - worst customer service ever

Worst customer service ever. I have communicated multiple times that it should be a NEW installation, yet I have only received the router and no installation. I have been waiting over a month for the installation. I have logged multiple tickets with their customer helpdesk, and I have yet to receive and feedback or communication. Now I am getting a bill for the month of March but I do not even have internet or fiber connection as they messed up several times. I am sick and tired trying to reach out to this company with no avail. I am done and want to cancel my contract, but I can't even do that because no on from this *********** company will assist me.
