From what I was told, Virgin's fault fixing only happens when a large number of people in a given area complain to them using the online reporting tool.
Unfortunately for us gamers, that means the issue will never be fixed.
As discussed with the engineer at the weekend, myself and a friend are probably the only two young adults on the postcode, so all the parents around here and older generation watching their Love Island won't have a clue that their low bitrate ITV hub stream is dropping during and episode.
I'm going the route of asking for a price match with BT's max package, and then taking out a separate BT line for gaming, or if they refuse that I'll be leaving Virgin altogether and going with an older BT line until they get FTTP here.
