It looks to me that there was an issue ( caused by you ) that’s been ‘fixed’ , but not necessary very well explained, if you called Sky yourself to cancel their service, then contacted BT , the BT order would fail , because of the Sky order to cease your service that you incorrectly asked them to raise, you didn’t need to contact Sky yourself, you should leave that to the new provider, BT in your case, to advise Sky.
BT advise you that the BT order is being rejected because of an order already in place , you contact Sky yourself ( BT cannot do this for you ) , Sky understand the mistake you made and cancel the cease you requested, thus clearing the way for the BT order to proceed , BT then resubmit your original request to join BT , because there is no longer a ‘Sky’ order in the system blocking it , the BT order now goes through.
It does now appear that the migration is due to take place 1st /2nd. February , nobody lied to you , migration between providers is not a process that everyone is familiar with , so it can go wrong or be delayed when people incorrectly tell their old provider they are leaving themselves , instead of simply contacting the new provider and leaving everything to them.
