Did you basically plug the Sky router into exactly the same place as where the BT router was (so you swapped one for the other ) , and no installation work necessary by Openreach or City Fibre , so whatever Openreach network you were on with BT , was the same with Sky, and your Sky broadband and Sky phone service worked pretty much immediately after you replaced the BT router with the Sky router ?
If that’s the case , and you used the OTS system to manage the migration, did you get an impact statement from BT ?
Part of the OTS process is as soon as the new company identify your service and indicate a migration is being considered , the losing provider automatically send you a notification showing any termination charges (if still inside a contract) and what equipment needs to be returned etc , that’s the ‘impact’ of what the migration will mean to you …if you never got that impact statement, ( and as you never received any information about returning the BT router ) , suggests BT were never automatically told you were off to Sky , if that was the case the initial fault was not with BT , if you did get an impact statement then BT were culpable.
