The losing provider , more so with OTS than the previous NOTs system has no veto on switching , so there is no BT involvement until BT are advised that the switch has been completed and they arrange your final bill …VF are giving you the runaround if they are saying the issue is with BT .
If there is an issue with your address with Openreach’s records ( this only applies if you are intending to use VF on Openreach rather than VF on City Fibre ) , that may need looking at by Openreach , but you haven’t said that’s the issue , so basically the issue is between you , VF and OTS ,
