Agonizing experience with Zoomfibre

Zoomfibre took my details and installed a line in December, its been an agonizing 3 months of me being sent from pillar to post. Whenever i call Zoomfibre, they send me to Supersonic (claiming that they are the primary network provider) and when i call Supersonic they send me back to Zoomfibre. Clearly I am the clown here, for having trusted Zoomfibre with my personal details. I have tried to ask Zoomfibre to release my line and they claim that their company is not the one that blocked my line. Meanwhile, they are the only company that I shared my details with. So now I don't have a fibre service and additionally, I cannot access another another service provider because they have blocked me.
