SuperSonic is a disgrace!

We move my fibre line from Vox to SUpersonic last year because I saw SuperSonic ranked 2nd for customer satisfaction on myBroadband, but unfortunately the honeymoon didn't last long! We requested another fibre installation for another property on the 20th of January 2021, we received no update or communication on the progress until I called SuperSonic around the 9th of March to follow up! I was informed then, no job was logged for our installation, this is more than a month later! I requested to speak to a supervisor or manager and held the line for about 5 more minutes when the consultant came back to tell me the manager can't talk to me I must just wait for a call from their project team before the end of the day. I was shocked and angry, but worse, to date I never received that call from their project team! I called again during the week of the 15th of March, the consultant gave me a reference number and said I must call Frogfoot to follow up, I called Frogfoot and was told "call SuperSonic, we don't deal with end users", I called SuperSonic again and was told they couldn't find any job logged for our installation, they logged with the project team that will contact me. The following day we received an email asking us to submit proof of address (despite being existing customer of SuperSonic), we submitted the proof of address since the 18th of March to an email address that says noreply! I called them to find out if they received it because there was no other email to send it to, they confirmed receipt. Now we're still waiting, absolutely NO COMMUNICATION from them whatsoever! At the time I'm typying this review it's been 68 days since we requested installation, no call from them, no communication indicating when the installation will happen and the mobile router they sent us to use in the meantime is completely useless, constantly dropping off Zoom meetings and online classes; now we have to buy data to use our phones as hotspots. I don't even know if I should just cancel everything including my contract at the other house and buy mobile data or wait until Jesus comes! I'm so angry and disappointed at SuperSonic!
