This is a BT Retail customer. It would be an Openreach engineer not BT Retail who would have visited. This forum has nothing to do with Openreach or Sky.
If you want to move your service from Sky to BT Retail, then provided you are out of contract with Sky, you simply place an online order with BT Retail, and they will do everything else, and will also let Sky know you are moving.
You must do it online to qualify for any rewards.
