Welcome to the community,
Could you please send me a PM (private message) with your CID (customer identication number) or your mobile phone number so can look at this service for you
I would like an answer to this question too. I would assume that when my landline number was ported to TPG NBN from Telstra that Telstra would have been notified to cancel my landline account, as occurs when a mobile number is ported.
Do I need to notify Telstra to cancel my home phone account?
