I had to move to another flat (already has UFB connection) this weekend so I had no choice but to leave bigpipe.
My billing date was yesterday but I still needed connection until this Sunday. I was given no choice other than paying for another month so I did that.
I made the payment and was scheduled to be disconnected on 9th Sept.
I got disconnected today so I email support and Jeff replied saying they messed up the disconnection date so now wait for couple of days for Chorus to reconnect or get refund and bugger off.
so screwed
