Caller: NBN fibre installation

NBN fibre installation call to make sure appointment is still good and to give a rundown of the procedure.

Caller: NBN

NBN call to confirm scheduled appointment is still good.

Caller ID appeared as "Google." As per one of the messages above, the caller claimed that it was about an NBN installation I had booked. The person (obviously from an Indian call centre) used my first name in her introduction. I replied that it was not necessary as I knew about the process and the information was available on-line. The person then said they wanted to check that they were speaking with me and gave my full name before asking for more details to confirm my identity. I hung up.
From two previous experiences re. NBN connections, I am wary, as these seem to attract a lot of weird communications from Indian call centres which make it hard to know whether they are real or bogus.
