Welcome to the community and thank you for getting in touch K_Oliver.
I am very sorry to hear this has happened.
It sounds like the people purchasing your house may have contacted us to arrange services which has then caused the disconnection.
in a situation such as this it can take up to 72 working hours for the services to be reconnected.
If you find that the service has not returned by this time tomorrow, please pop a post on this thread and let me know and we can get this looked in to.
Thank you for your patience.
Nat
