Broadband is useless

[Jason9494]

Had sky broadband 4 weeks now and already had to change router because there was a fault and now I'm receiving 330mbps ever day not 900 and not the guaranteed minimum of 600 my WiFi signal is poor  I'm absolutely fuming with how sky broadband has treated this as I've phoned up twice now been paying pull price for 2 months and had nothing but problems I've had enough either an engineer comes out and sorts this out or cancel my

sky broadband band with money back it's a joke

@Jason9494 Can you do the 30 day service checker history that sky see's and post that up, broadband and > to expand and view.

How are you measuring the 300Mb/s that you get for checking?
