From what I can tell, from my dealing with CS and in this thread you have no idea of the cause of the outage with Netflix streaming.
It would really be nice if you keep us inform or at least been honest about it. Or put a statement on the VIginMedia Website so that we know that you are working to resolve the issue. Instead, there is no information what's so ever and you are claiming that everything is all Hunky Dory when we call CS.
The frontline staff will almost certainly not know the reason for the outage, because they haven't been told. The phone staff not being informed that there is an issue is poor, but VM have form for this kind of thing not filtering through to the call centres. No point criticising the forum staff for a decision or a lack of action that is taken by managers way above them.
Not sure how a statement on the VM site is any better than a staff response here. Personally I'd rather the staff spent time collecting information via the forum in order to pinpoint the issue and help to get it resolved. The more evidence VM have the more likely it is they will get it fixed. I can see that the @ModTeam are merging all similar posts into this thread which is a good sign that they are taking this seriously and collating information.
