If you have Starlink and a phone number you ported away from BT , that you access via Starlink , you must have used a third party VoIP provider to port your number , this will cease your BT service , although you haven’t really provided much information, it seems the communication you got from BT was a standard ‘sorry you are leaving’ , and if you were inside a minimum term , early termination charges are appropriate, this would be generated by the VoIP provider requesting your phone number to be ported into their network.
You still haven’t really clarified what it was you did and what you expected, if Starlink was intended to replace your BT broadband, and you moved your phone number to third party VoIP supplier, what was it you expected from BT to do (and what service if any they would continue to supply ) and why would you think ceasing your BT services wouldn’t involve early termination charges if you were quitting them before the minimum term had expired.
You seem a little defensive and appear not to want to give a comprehensive explanation of how you got to where you are , but it’s not a case of apportioning blame , simply getting the full story.
TBH based on what’s currently known , it’s difficult to see why you think you have been treated badly…the only thing possibly is you were told charges would be waived , but why would they do that if you quit before the minimum term was up ?
