New Line - Pay for Earlier Install Date?

[#1]

Hello,
I'm moving into a new home a week on Friday (18th). I've just placed an order with PlusNET and i've had a provisional line install date of the 29th October.
What are the chances usually of having this brought forward, either by asking nicely or paying? I really need an internet service to work from home, so apart from a 3G dongle i'm a bit stuffed!
Cheers
Matt

Hi Matt,
We always provide the earliest dates possible. We can always check to see if there is anything else though.
It seems there has been an issue with the line at your new property, we've updated you ticket which explains. You can view this at - https://portal.plus.net/wizard/?p=search
