So I phoned my current supplier and informed them.
Oh dear! If you called your current supplier to cancel, they will have put a cease,on the connection, which will have cancelled Plusnets order to transfer the service. They will now have had to replace the order to transfer once the cease has completed.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
