Poor Wi-Fi coverage upstairs, how do I get an extender?

[RellaCGS]

I have been using a Wi-Fi booster but it has just died. I thought Sky guaranteed coverage around the house so I need an extender. How do I ask for one? Any help please?

Sky loans wireless booster hardware free under the terms of the 'WiFi Guarantee' element of 'Broadband Boost' and the 'Enhanced Wall to Wall WiFi Guarantee' part of the 'WiFi Max' subscription supplement: they don't otherwise provide or sell them except to resolve issues with Sky Q. Inevitably some have leaked onto a certain auction site, but Sky won't offer support with using these. 

Confusingly the 'Wall to Wall WiFi Guarantee' doesn't actually provide booster hardware, and is essentially a sales lead generator for the supplements mentioned above.
