Non existent customer service

Good Evening,

I received a text message, notifying me of fibre installation and router collection that will be done and a deactivation of services on the Lte router. As far as I am aware there is no fibre installation done at my place, I emailed Supersonic on 27 September 2021, no response since I called contact centre where you are put on hold for 45minutes before an agent answers your call, to be told my case will be escalated to the project manager to callback, no call since. I anticipated the no callback, I also indicated to the contact centre agent, how will project manager callback if they cannot respond to an email.
