Fibre Service Providers Mafia style

The message below is a message i sent ZOOM Fibre who could not help saying they have nothing to do with end users. i am so frustrated.

"Please can someone assist me with a huge problem I am having with my fibre connection. Fibre infrastructure was completed towards the end of September 2021 in our area. I did not sign up with any service provider as I had intention to go with MWEB as they are my current service provider with ADSL, however without my proper knowledge a service provider came to my property and installed the line and router. I presumed it was Zoom and no particular provider. I then proceeded to make application with MWEB for a connection. This was done on the 29th September 2021. Since then I have been receiving messages from MWEB saying I need to discontinue services with my current service provider before they can connect me. I was very surprised as I had not signed with any other service provider. I have tried chatting with various people at ZOOM with out any solid assistance. They eventually told me that I am subscribed to Accelerit Fibre, which I never app**** with. I have never signed any contract or debit order with them and now I am been told that they will not remove their equipment and I am liable. I have never used their service since the installation and they need to prove that I signed up with them. It is unacceptable that they just go and do an installation and hold someone to ransom. I need them to remove their equipment so that I can get the service provider I want for the installation. I refuse to be held ransom to this type of ******ion. How many other people are they doing this to. Please assist as its been 4 months I have been trying to sort this out."
