Hi @nancelle ,
Thanks for raising this to us. I would love to help disable the call waiting feature of the NBN service. To proceed, PM me your account details (Username/customer ID together with the address on file) together with the address on file.
I have a current NBN plan with TPG and I would like to turn off call waiting on my digital voice service. TPG Technical Services told me I would need to talk to TPG Customer Service, who then told me that I would need to look at the instruction manual for my phone, which told me that I needed to contact my service provider... I am going around in circles!
