Fiber installation after moving house

Extremely disappointed in Supersonic. We have moved houses 10 days ago. To make sure we would have internet asap after moving in, we contacted Supersonic before moving, to make sure our new place was fiber ready, and asked if there was anything we could do to speed up the progress. We were told it would take a phone call and a 24 hour wait.. We have been on the phone with the Supersonic helpdesk every single day since we have moved in. Every time we call, we have to explain our situation, no one seems to be able to find out what the status of our installation is. We have phoned the network provider of our new house ourselves (as Supersonic promised to do this but somehow seemed to struggle with it); they confirmed us our house is fiber ready, and ready for the fiber order from Supersonics side. Yet nothing seems to happen Supersonics side. We are a family of 3, all of us are obliged to be working from home.. We are desperate and extremely disappointed in Supersonic!
