I know this may have been around for some time.  Wife got a call from "Spark" saying they want to discuss something about her phone account.  I asked her to pass the phone to me and the lady on the other side spoke in speed saying that we have landline and broadband with Spark (which a lot of kiwis do).

I asked her to talk slower and she asked me how I use the internet?!  I said it is my business about how I use my internet and I ask her firmly, but politely to get to the point.

Then she said thanks for yourtime and hung up.

Just a heads up this could be a scam.
