Long ongoing outage, poor information

We lost our Broadband connection on Saturday (28 June). The fix date was given as 1 July PM - and that remained the same every time I checked the status over the next few days. I contacted Virgin via the online messenger yesterday (30 June)  and was told it would be fixed today (in hindsight I assume the person that responded was just quoting the fix date from the status). However, shortly before the fix date/time today I had an update to say that the fix was now 8 July. Resorted to the messenger again to try and find out more details, but I am just told that the fault is 'high'. I have been advised about auto-compensation, but do I have any guarantee that it will be 8 July? For such a long outage this is really poor information and this is impacting upon my ability to work. Is there any way to get meaningful updates beyond the service checker and what feel like rather uninformed updates via the messenger? (Up to now the broadband has been very reliable and there has never been an outage of this length since I have been a customer.)
