Hi @johncstewart ,
Welcome to the community!
Thannks for raising this to us, we'd love to help and raise this to our Account Specialists to investigate the excess charges, shoot me a private message with your account details (Username/Customer ID) together with the address on file.
3 new excess charges showed up related to home phone service. I have never used this phone service with my unlimited NBN. I need more information on these excess charges. Thanks
