Another update incase anyone is interested
Just noticed Plusnet have a special offer on their fibre. So i called sky and mentioned this offer. Said i was thinking of going with plusnet instead...
Long story short, sky offered me the 40/10 fibre for £10 a month ( reduced from £20 )
And have also refunded me the £50 connection charge
Also the sky router was dispatched today
The guy on the phone also mentioned sky should have some offers on the fibre pro service in the next few months. I guess reducing the price to be competitive against BT/plusnet. And the line saver will be back
