God there is 14 days cool off period.
Thanks guys for all the suggestions!
Great community!!
Just remember the 14 days starts the day you place your order, not the day the service goes live.
edit: Plusnet website suggests it's when the kit is received.
With most ISP's it's the day of ordering. BT start it the day the service goes live but that's a fairly recent change.
2nd edit: I was correct, 14 days from the day you order.
It's only tv and phone services from Plusnet that start the day you receive the kit.
