Hello janbake
Thank you for taking the time to contact us in regards to the changes to your landline, we understand the confusion this can cause and are happy to help via the forums. Welcome to the community.
We're eager to get this looked into for you, what was the reason given for the need for an engineer? Was this due to the line extensions? We can see you spoke to the team just a week ago and an adapter was advised as being sent, have you received this?
