Don’t trust the engineer that comes to your house. I moved my broadband from BT to Sky and an Openreach engineer fitted the new box. He then offered to return the old BT equipment to BT. So I let him take it all. Then a week or so later BT was asking me to return the equipment or pay £80. I called them to say I had given it to the Openreach engineer to return. They said that engineer had nothing to do with BT. I then called Sky who said they could not help. What amazed me was no one took responsibility for sending a total stranger to my house to basically steal my property and you can’t contact Openreach directly as they only deal with companies not customers
