They've made me do all sorts of unplugging, plugging in again, resetting and even had BT test the line, all to no avail. (BT engineer said the line was totally fine, it was either my router or a glitch at Sky's servers). Naturally, Sky denied both of these possibilities and refused my request for a replacement router.
Well, it finally went down completely and I've been left twiddling my thumbs waiting for them to "FIX IT".
How did they fix it? They sent me a new router!
JOB DONE!
Guess who's looking into swapping to a new phone and broadband provider?
