Fibre Instability & Seemingly no follow up service for cancellations.

Honestly, I have had the worst time the past 2 months with Supersonic. My fibre keeps dropping and is entirely unstable. Working from home has become a nightmare. I have tried cancelling but the process is EXTREMELY slow, I put in a cancellation request on 15 September, to date (5 October) I have no indication as to what is going on regarding the final invoice and when the last day of service will be. I just sat on a hold, trying to get through to cancellations for LITERALLY 1 hour. I mean that is just ridiculous! If I could give them less than 1 star I would. SHOCKING SERVICE!
