Totally sorted a couple of days ago, plus a generous compensation as well.
I called Telstra/Clear to double check there services there where being cancelled and was asked why my olds where leaving Telstra/Clear. I said, 10 times more data, Linespeed 2 times faster, 18 more smartphone features and only half the price.
If these are the problems you have with the connection jeez... Guess you pay what you get for
I moved house this past weekend, called SS two weeks in advance with the details and it was all set to happen last Friday. As well as moving I would be swapping plans from the naked dsl plan to a homeline + 250GB plan. Last week on Monday (while in Sydney) I found out I had given them (and everyone else) the wrong address and had also given them the incorrect date that the previous tenant was getting her services disconnected. Got hold of a very unconfident sounding CSR and updated the details but still thought it was all going to go horribly wrong, but figured thats what I get for giving out the wrong info.
Got 2 texts from the Chorus tech on the Thursday saying it had all be done and a couple of confirmation emails from SS later that day. This had me worried as the previous tenant had said she wasn't getting her Telecom service disconnected until Sat!
Anyway, get back to NZ on Sat evening, into the house on Sun and first thing plugged the modem and phone in to find everything was working perfectly fine. Yay.
I suspect most new or moved connections happen without a problem and its only the bad ones we hear about. Certainly in my case, Slingshot were great. :D
