So I've had a few issues with the NBN set up and my phone line. The phone was crackling and the NBN wouldn't work and so TPG sent out a technician who found it was water damage in the lines outside. They sent another person who fixed it and I got a text saying I needed to activate the NBN modem. I did, and it still isn't working. The lights are flashing, except for one, and there's a clicking noise. I sat on the phone for half an hour and the person said I needed to talk to a case manager and transferred me, but then the voice on hold said there were too many people so it hung up on me. I tried calling again but an hour in and nothing. Any help from someone would be great.
