Supersonic holds you hostage - Bad service

We "joined" Supersonic at the end of Jan 2021 when we moved to a new house. We were told that they'd deliver a modem to temporarily use until they connect our fibre. Two weeks passed before a modem arrived. Once the modem arrived we could use internet. By mid March our fibre had still not been connected after numerous calls to Supersonic's call centre (who are useless). My husband then called them after waiting for weeks and cancelled the service with them. He then signed up with a different ISP. Two days later Vumatel arrived to connect our fibre (they were sent by Supersonic after we cancelled). We sent them away because we don't want this service anymore because of the pathetic, non-existent customer service.

The service has still not been cancelled My husband calls the call centre twice a day, every day There is no manager available, always in meetings

Order still not cancelled

We can't get our new ISP to connect us to the new fibre as Supersonic has now reserved the line (after more than 2 months).

Please can you just cancel the service. We don't want to use you any longer, you are unreliable and unprofessional. Worst decision ever.
